In this article, numerical investigations on mixing and heat transfer of solid refused fuel (SRF) particles in a bubbling fluidized bed are carried out. The numerical model is based on the Eulerian-Eulerian approach with empirical submodels representing gas-solid and solid-solid interactions. The model is verified by experimental data from the literature. The experimental data include SRF vertical distribution in SRF-sand mixtures of different sand particle sizes ( d pm = 654, 810 and 1110 μ m) at different fluidization velocities ( u∕u mf = 1.2-2.0). We proposed magnification of drag force exerted by the gas on SRF particles based on Haider and Levenspiel (Powder Technol 58 (1): [63][64][65][66][67][68][69][70] 1989) drag coefficient. The proposed model shows good agreement with the experimental data at high fluidization velocities ( u∕u mf = 1.5-2.0) and poor predictions at low fluidization velocities ( u∕u mf = 1.2-1.5). Heat transfer results showed that the present model is valid and gives good agreement with the experimental data of wall-bed heat transfer coefficient.
