Abstract

Abstract

The DEM approach is used to simulate the random distribution of fuel spheres.The purpose of this work is to study the flow fluid and heat transfer by means of CFD techniques.Analysis shows that the pressure is lower,but the velocity,eddy and temperature are higher in the clearance.The pressure,eddy and heat transfer coefficient are increased with the porosity reduction,but velocity is reduced with the porosity reduction.
