Abstract

Abstract

In this paper, the detailed local flow and heat transfer phenomena are investigated by computational fluid dynamics(CFD) for the locations that may have the maximum pebble temperature. The distributions of temperature on the surface or in the fuel pebble, and the velocity field near the fuel pebble are obtained and analyzed. Results are compared with that acquired by in-house code FRAC and the maximum relative error is 2.9%, which preliminarily proves the accuracy of FRAC. This study can provide useful information to the experimental and mechanism research of FHR.
