Cardona, Luis F. published the artcileExtension of a group contribution method to predict viscosity based on momentum transport theory using a modified Peng-Robinson EoS, SDS of cas: 110-42-9, the main research area is group contribution method viscosity momentum transport theory PengRobinson EoS.
In this work, a semitheoretical model based on the momentum transport theory is generalized through the development of a group contribution method. Viscosity data for temperatures between 13.95 and 950 K and pressures from 1.00 x 10-3 bar up to 1.00 x 104 bar were used to develop and to validate the model. To perform viscosity calculations, the model requires d. and residual enthalpy that were obtained from a modified Peng-Robinson equation of state. Also, the model has one adjustable parameter that can be estimated form the group contribution method. Viscosity was calculated for 256 substances including 95 non-polar and 161 polar compounds In total, 23 organic families were considered. Average deviations below 6.67% were calculated The performance of the model was compared with those of other models reported in the literature. Calculations were carried out to include the saturation and single-phase regions. In general, it can be considered that the proposed model describes viscosity adequately using only one adjustable parameter.
