Abstract

In this paper, numerical and experimental analysis of the heat transfer between an immersed heater and a cone bed of sand particles were carried out. A 3-dimensional model using the Eulerian-Eulerian model coupling with kinetic theory for granular flow was used to simulate heat transfer and related bed flow characteristics. The investigation was carried out at different inlet gas velocity represented by the fluidizing number, (the ratio between inlet gas velocity to minimum fluidizing velocity) and different particle-wall boundary conditions. Both the experiments and numerical simulation results showed that the heat transfer coefficient and bed expansion ratio increased with increasing inlet gas velocity. For particle-wall boundary condition, applying no slip condition resulted in best heat transfer coefficient and bed expansion ratio compared to experimental results.
