The numerical modeling of the tube turbulent gas–drop flow with phase changes

Abstract

Within the concept of heterogeneous-continuum mechanics, the present work numerically, in the two-velocity, two-temperature Euler approximation, examines the turbulent flow of an air–drop mixture through a duct. Effects due to drop evaporation, deposition of drops from the flow onto the duct wall, heat transfer due to direct contacts of drops with the wall, the stochastic motion of drops, and non-isotropic turbulent fluctuations of their velocities on the heat- and mass-transfer processes in the turbulent flow are studied.
