Li, Han published the artcileTowards developing high-fidelity yet compact skeletal mechanisms: An effective, efficient and expertise-free strategy for systematic mechanism reduction, SDS of cas: 110-42-9, the main research area is dodecane skeletal mechanism combustion computational fluid dynamics.

This study explored the potential of integrating reduction methods with different features for systematic mechanism reduction Based on our two recently developed/optimized reduction methods, sensitivity anal. method and unimportant reaction elimination, a generalized strategy for systematic reduction of large detailed mechanisms was proposed. This strategy was firstly used to reduce the detailed mechanism for n-dodecane containing 2,115 species. A compact skeletal mechanism with 150 species was obtained, and close agreement with the detailed mechanism was achieved. Next, the detailed mechanism for a three-component biodiesel surrogate with 3,299 species was successfully reduced to a skeletal one with 179 species. Extensive validations were performed to show the high fidelity of the obtained skeletal mechanism. After demonstrating the effectiveness and reduction capability of the proposed strategy, its efficient and expertise-free features were elaborated. This strategy not only greatly lowers the threshold for reducing large detailed mechanisms, but also significantly saves the computational cost and human time effort in mechanism reduction process, while exhibiting satisfactory reduction capability to generate high-fidelity yet compact skeletal mechanisms.

Daridon, Jean-Luc published the artcileSpeed of Sound, Density, and Related Thermophysical Properties of the Methyl Caprate + Methyl Oleate Binary System from 0.1 MPa to 70 MPa at 303.15 K, Quality Control of 110-42-9, the main research area is methyl caprate oleate binary system thermophys property.

In this work, we reported values of speed of sound and d. of the Me caprate + Me oleate binary system over the whole composition range from 0% to 100% for pressures ranging from 0.1 MPa to 70 MPa and at 303.15 K. A pulse-echo technique working by reflection was used to measure the speed of sound w at 3 MHz. A vibrating U-tube densimeter was used to obtain d. data. From the combination of both these measurements, the isothermal and isentropic compressibilities were determined Finally, the speed of sound mol. weight product and the mol. compressibility Κm, also known as Wada’s constant, were calculated and represented as function of molar fraction in order to determine the best combining rule for predicting the speed of sound of the mixture from pure Fatty Acid Me Ester properties.

Wang, Wenyu published the artcileAutoignition study of methyl decanoate using a rapid compression machine, Safety of Methyl decanoate, the main research area is autoignition methyl decanoate rapid compression.

Me decanoate (MD), a widely used surrogate of biodiesels, was investigated for its autoignition characteristics using a heated rapid compression machine (RCM). In this study, the ignition delay times (IDTs) of MD were measured at the compressed pressures of 5-20 bar, equivalence ratios varying from 0.53 to 1.60 and compressed temperatures of 633-855 K. An obvious two-stage ignition behavior was observed at low temperatures and typical neg. temperature coefficient (NTC) phenomenon of total IDT was exptl. captured. The influences of compressed pressure, fuel and oxygen content, and nitrogen concentration on ignition delay times were systematically studied. The simulation results of Herbinet’s mechanism and Grana’s mechanism under variable volume simulation were compared with the exptl. data. It is found that the two mechanisms qual. predict the autoignition features of MD but still need further optimization. In addition, reaction pathway anal. and sensitivity anal. were conducted to offer further insight into the low-to-intermediate temperature autoignition chem. of MD.

Kuti, Olawole Abiola published the artcileSpray combustion simulation study of waste cooking oil biodiesel and diesel under direct injection diesel engine conditions, SDS of cas: 110-42-9, the main research area is spray combustion simulation waste cooking oil biodiesel diesel engine.

Spray combustion characteristics of waste cooking oil biodiesel (WCO) and conventional diesel fuels were simulated using a RANS (Reynolds Averaged Navier Stokes) based model. Surrogates were used to represent WCO and diesel fuels in simulations. N-tetradecane (C14H30) and n-heptane (C7H16) were used as surrogates for diesel. Furthermore for WCO, surrogate mixtures of Me decanoate, methyl-9-decenoate and n-heptane were used. Thermochem. and reaction kinetic data (115 species and 460 reactions) were implemented in the CFD code to simulate the spray and combustion processes of the two fuels. Validation of the spray liquid length, ignition delay, flame lift-off length and soot formation data were performed against previous published exptl. results. The modeled data agreed with the trends obtained in the exptl. data at all injection pressures. Further investigations, which were not achieved in previous experiments, showed that prior to main ignition, a first stage ignition (cool flame) characterized by the formation formaldehyde (CH2O) species at low temperature heat release occurred. The main ignition process occurred at high temperature with the formation of OH radicals. Furthermore, it was observed that the cool flame played a greater role in stabilizing the downstream lifted flame of both fuels. Increase in injection pressure led to the cool flame location to be pushed further downstream. This led to flame stabilization further away from the injector nozzle. WCO had shorter lift-off length compared to diesel as a result of its cool flame which being closer to the injector. Soot formation followed similar trends obtained in the experiments

Sui, Meng published the artcileStudy on the mechanism of auto-oxidation of Jatropha biodiesel and the oxidative cleavage of C-C bond, Recommanded Product: Methyl decanoate, the main research area is biodiesel methyl linoleate hexanal oxidation Jatropha.

Jatropha biodiesel was obtained according to the continuous preparation process which included vapor esterification – transesterification – methanol steam distillation Accelerated oxidation of small Jatropha biodiesel was obtained by the Rancimat method. GC-MS and liquid phase micro-extraction were used to study and analyze the components in the oxidation process of Jatropha curcas biodiesel. The electronic effects of the related reactants and products were calculated by d. functional theory, followed by the deduction of the related chem. reaction paths. Exptl. investigation shows that Me linoleate is the main factor affecting the oxidation stability of the Jatropha biodiesel. The main volatile products at the initial stages of the oxidation of Me linoleate are hexanal, Me octanoate, styrene, and 2-heptenal. The cis/trans-3-octyl-oxiranyl octanoic acid Me ester (18.03% yield) is produced by the reaction of peroxy acid and Me oleate during the oxidation of Me oleate. The hydrogen extraction reaction is difficult to occur, and the oxidation reaction energy barrier is relatively high due to the relatively large bond energy of the C-H bond in the Me stearate mol. In this manuscript, the auto-oxidation mechanism of the biodiesel fatty acid Me esters at the initial stage of oxidation, the path of oxidative cleavage of the C-C bond of Jatropha biodiesel and the formation process of ethylene oxide structure are obtained through DFT calculation and anal. of the oxidation products.

Ramalingam, Selvakumar published the artcileInfluence of Moringa oleifera biodiesel-diesel-hexanol and biodiesel-diesel-ethanol blends on compression ignition engine performance, combustion and emission characteristics, Synthetic Route of 110-42-9, the main research area is Moringa biodiesel hexanol ethanol blend ignition engine performance.

In the current work, the influences of Moringa oleifera biodiesel-diesel-hexanol and Moringa oleifera biodiesel-diesel-ethanol blends on compression ignition engine characteristics were exptl. investigated. Experiments were conducted on a diesel engine at 0%, 25%, 50%, 75% and 100% load conditions run at a constant speed of 1500 rpm. The results revealed that B90-D5-H5 acquired the lowest BSFC and maximum BTE of 0.375 kg kW-1 h-1 and 28.8%, resp., and B100 had the highest BSFC of 0.425 kg kW-1 h-1. B90-D5-H5 had the highest cylinder peak pressure of 74 bar at 4°CA aTDC. The maximum heat release rate (HRR) and longer ignition delay (ID) period of 44 J per °CA and 14.4°CA, resp., were attained in the B90-D5-H5 blend. At 100% load condition, the lowest amount of carbon monoxide (CO) of 0.32% volume was acquired in the B80-D5-E15 blend. The maximum nitric oxide (NO) emission of 1090 ppm was also acquired in the B80-D5-E15 blend. B100 had the lowest NO of 846 ppm; B80-D5-E15 had the lowest unburned hydrocarbon (UBHC) emission of 34 ppm at 100% load and the lowest smoke opacity of 34%. Biodiesel-diesel-alc. blends improve engine performance and decrease emissions compared to the conventional diesel. The utilization of biodiesel-diesel-alc. blends reduces the consumption of diesel. Hence, ethanol and hexanol are recommended as potential alternative additives in biodiesel-diesel blends to improve engine performance and reduce emissions.

Potrich, E. published the artcileThermodynamic properties of formation estimated to biodiesel esters using gaussian quantum chemistry software and group contribution method of constantinou and gani, Recommanded Product: Methyl decanoate, the main research area is biodiesel ester Gaussian quantum chem constantinou gani thermodn property.

A lot of recent research has focused on the study of biocatalysts and nanocatalysts to improve biodiesel production However, knowledge of the thermodn. properties of the reaction components is necessary. In this work, the enthalpy of formation and Gibbs free energy of formation for Me to pentyl esters were calculated using the Gaussian quantum chem. software (model B3LYP/6-31G(d, p)) and the group contribution method of Constantinou and Gani (MCG). The values obtained by both methodologies present certain differences in relation to the values in the literature. Thus, three correction parameters, which were based on the number of atoms of 26 different mols., were estimated by minimizing the error function and later used to extrapolate the results to larger mols. of interest. After the use of the correction parameters, the mean deviation between the exptl. and calculated values by Gaussian was 0.723% for enthalpy and 1.087% for Gibbs, whereas for MCG, it was 1.324 and 2.540%, resp. As the methodol. proved to be efficient, the thermodn. properties of the formation of 23 esters that compose the biodiesel were estimated These properties are of great importance, mainly for the calculation of chem. equilibrium and reaction data in the development of new catalysts.

Lin, Xiaocheng published the artcileSelf-solidification ionic liquids as heterogeneous catalysts for biodiesel production, Synthetic Route of 110-42-9, the main research area is solidification ionic liquid heterogeneous catalyst biodiesel.

Different from the common ionic liquids (ILs) as homogeneous catalysts, solid ionic liquids (SILs) as heterogeneous catalysts are simply fabricated herein via an efficient one-step reaction for biodiesel production Specifically, low-cost aliphatic amines containing secondary and/or primary amine groups are selected as the starting materials followed by the reaction with 1,3-propane sultone under mild conditions to graft sulfonic acid (-SO3H) groups onto the final products. The -SO3H groups are divided into two types: the bonding -SO3H groups (zwitterion arising from the hydrogen bond between sulfonic acid groups and amine groups) make the products turn solid while the free -SO3H groups endow the products with catalytic activity. Such solid ionic liquids (SILs) present pronounced activity, excellent stability and reusability as heterogeneous catalysts in esterification of free fatty acids (FFAs), indicating great potential in biodiesel production because of their high performance and low cost.

Wang, Pengfei published the artcileDevelopment of a decoupling physical-chemical surrogate (DPCS) model for simulation of the spray and combustion of multi-component biodiesel fuels, Computed Properties of 110-42-9, the main research area is spray combustion multicomponent biodiesel fuel DPCS model.

A decoupling phys.-chem. surrogate (DPCS) model was established for simulation of the spray and combustion characteristics of multi-component biodiesel fuels. In the DPCS model, the phys. and chem. properties of biodiesel fuels are described sep. For the case study of soybean Me ester (SME), the phys. properties are represented based on the five primary components, i.e., Me palmitate, Me stearate, Me oleate, Me linoleate, and Me linoleate. Meanwhile, the chem. kinetics of SME are described by a skeletal reaction mechanism composed of Me decanoate, Me 5-decenoate, and n-decane. Furthermore, an improved quasi-dimensional multi-component vaporization model was applied to predict the fuel vaporization process. To validate the DPCS model, the predictions from the present model and the previous models are compared with the exptl. data, including the liquid penetration in a constant-volume bomb and the combustion and emission characteristics in a premixed charge compression ignition (PCCI) engine. The results indicate that the predictions of the DPCS model agree better with the measurements than the previous models considering only the single-component phys. and/or single-component chem. properties of SME on the spray, ignition, and combustion behaviors. It is found that the ignition delay and heat release rate of PCCI combustion are dominated by the evaporation rate of SME and the fuel-reactivity stratification within the cylinder. By considering the multi-component properties of SME, the combustion and emission characteristics can be satisfactorily reproduced by the DPCS model. Meanwhile, the computational time can be well controlled due to the simplification of the phys. and chem. surrogate sub-models.

Yang, Liping published the artcileAnalysis of cycle-to-cycle variations in a common-rail compression ignition engine fuelled with diesel and biodiesel fuels, Recommanded Product: Methyl decanoate, the main research area is diesel biodiesel fuel combustion compression ignition engine.

Using wavelet and fractal theories, cycle-to-cycle variations (CCVs) in a common-rail compression ignition (CI) engine have been investigated at engine loads of 25% and 50%, biodiesel blend level was from 0% to 100%. Wavelet power spectrums and singularity spectra were calculated to identify the dominant oscillatory combustion modes and multifractal complexity. Reaction paths and component consumption sensitivity of n-heptane and Me decanoate were studied to reveal the effect of biodiesel blend level on the combustion process of diesel fuel. Results reveal that the effect of biodiesel blend level on the CCVs is more significant at a low load, even when biodiesel blend level increases to 20%, the coefficients of variation decreases from 3.99% to 1.57%. The CCVs exhibit multiscale dynamics for all tested cases, and persistent high-frequency oscillations appear around a 16-cycle period persisting over the entire or several hundred of the engine cycles. As the biodiesel blend level increases, the periodic bands with the highest power were interrupted and combined with lower-frequency and high-frequency intermittent fluctuations. However, for the higher load, the dynamics of CCVs are mainly displayed in an intermittent fashion. The larger broadness of singularity spectra at higher engine loads suggests a higher degree of multifractality. For all of the tested cases, the dynamics of the CCVs behave like antipersistent walks. As a oxygenated fuel, biofuel substitution leads to increase of c7h15-1 concentration and radicals such as OH, O and H2O2, which are beneficial to decrease ignition delay and accelerate the chem. reaction rate of diesel fuel, and therefore inhibit the CCVs.
