Abstract

The convective heat transfer to a flowing, cohesionless granular material has been studied experimentally. Heat-transfer rates were measured for two materials from a heated plate installed in the floor of an inclined, open chute. The variable parameters were the bed depth and the mass flow rate.

At relatively small flow rates the heat-transfer rate increased with velocity in agreement with earlier studies. As the mass flow rate continued to rise however, it was discovered that the heat-transfer coefficient for a given bed depth reached a maximum and then decreased.
