Temperature Distribution of the Bed during the Second Falling Rate Period of Drying

Abstract

The temperature distribution of the bed of the granular materials at drying during the second falling rate period was calculated by the analytical solution of the equation of heat conduction. The equation of heat conduction during the second falling rate period became the differential equations with moving boundary. The heat-balance integral method was applied to solve this problem which consists of a variable heat flux at surface. The calculated results by the analytical solution were displayed and compared with the numerical solution and also with the experimental ones.
