Numerical Simulation of Unsteady and Periodic Motion Heat and Mass Transfer of a Highly Concentrated Granular Medium in a Coaxial Bunker

摘要

This paper presents numerical simulation of unsteady and periodic motion heat and mass transfer of a highly concentrated granular medium in a coaxial bunker. Mathematical model with variables vortex-stream functions was developed. Heat and mass transfer in highly concentrated granular materials at different time steps was studied for Re=0.25 and Pr=10 with periodically variable density of the heat flow.
