Crossover description of transport properties for some hydrocarbons in the supercritical region

扫码查看
In the present study, by defining new representative equations based on the transport crossover functions stemming from the application of renormalization group theory to the transport phenomena, as well as using Perturbed Chain Statistical Associating Fluid equation of state to calculate equilibrium quantities and their partial derivatives in and out of the critical regions (up to 2pc) to obtain thermal conductivity and diffusivity of some hydrocarbons. The results show that in the critical regions a good consistency with the available literature data is obtained, the AAD% of both thermal conductivity and diffusivity of the studied hydrocarbons ranged from 1.5% to 5%.
