In this paper, the hydrodynamics and wall to bed heat transfer of a gas?solid flow in a conical fluidized bed were simulated using the Eulerian-Eulerian model. Sand with a particle diameter of 560 μm was used as a bed material, and its properties were calculated by applying the kinetic theory of granular flow (KTGF). Different amounts of slip between the particle and wall were shown by varying the specularity coefficient. The effects of specularity (0, 0.2, 0.5, and 1.0) on hydrodynamic and wall to bed heat transfer at a superficial gas velocity of 2 m/s were investigated. It was found that the wall to bed heat transfer coefficient decreases with increasing specularity coefficient. Different values of the specularity coefficient resulted in almost the same hydrodynamic behavior near the wall and the center of the bed.
