CFD analýza toku partikulární látky

Abstract

In this study, CFD analysis of a particulate flow inside rotating kiln has been carried out. For this analysis purpose, ANSYS Fluent software is used. ANSYS Fluent offers various models for simulation of particulate flow and these models require various parameters to model behavior of continuous phase flow and dispersed phase flow. In this study, evaluation of time step, coefficient of restitution, spring constant and static frictional coefficient has been carried out. Inside rotating kiln, analysis of heat transfer between continuous phase and discrete phase has been modelled. There are many factors that can affect this heat transfer. These factors have been discussed in this study. A correlation describing heat transfer between particles and hot gas in a given geometry of rotating kiln was evaluated.
