Abstract: 

Heat transfer phenomena in batch fluidized bed dryer have been studied and analyzed using three phase model including solid phase, interstitial gas phase and bubble phase based on Rizzi model. New correlations of heat transfer coefficient to surrounding and convection heat transfer coefficient between solid and interstitial gas are being proposed. In addition, some modifications have been done according to the state of flow and particle properties.The model was used to study the effects of particle diameter, particle density and input gas temperature on Geldart group D particles. The numerical results of heat transfer such as solid and gas temperature distributions have been compared with the available experimental data and good agreement between them is observed.
