Considering the non-ideal behavior of
uids and their eects on hydrodynamic and mass
transfer in multiphase
ow is very essential. Simulations were performed that take into account the
eects 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 coecient denition, respectively, for both liquid and gas phases, the importance of nonideality
eects 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 signicant dierences between experimental data and simulation
results with more ideal assumptions.
