  3. Abstract:
  4. Considering the non-ideal behavior of fluids and their effects on hydrodynamic and mass transfer in multiphase. flow is very essential. Simulations were performed that take into account the effects of mass transfer and mixture non-ideality on the hydrodynamics reported by Bozorgmehry et al In this paper, by assuming the density of phases to be. constant and using Raoult's law instead of EOS and the fugacity coefficient definition, respectively, for both liquid and gas phases, the importance of nonideality effects on mass transfer and hydrodynamic behavior was studied. The results for a system of octane/propane (T = 323 K and P = 445 kPa) also indicated that the assumption of constant density in simulation had a major role to diverse from experimental data. Furthermore, comparison between obtained results and previous reports indicated significant differences between experimental data and simulation results with more ideal assumptions
