Improving Three Phase Modeling of Fluidized Bed Dryer

Improving Three Phase Modeling of Fluidized Bed Dryer

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 betwe...
