Numerical Calculation of Wall - to - Bed Heat - Transfer Coefficients in Gas - Fluidized Beds
A computer model for a hot gas-fluidized bed has been developed. The theoretical description is based on a two-fluid model ( TFM) approach in which both phases are considered to be continuous and fully interpenetrating. Local wall-to-bed heattransfer coefficients have been calculated by the simultaneous solution of the TFM conservation of mass, momentum and thermal energy equations. Preliminary...
متن کاملTwo Phase Heat Transfer Characteristics in a Vertical Small Diameter Tube at Sub Atmospheric Pressure
Two-phase heat transfer is experimentally examined through vertical small diameter tubes, D =1.45 and 2.8 mm using water under a pressure of 50 to 81 kPa and a natural circulation condition. The pool boiling correlation by Stephan-Abdelsalam and the thermosyphon boiling correlation by Imura, et al. predict the measured experimental data in the 2.8 mm tube with an error of -30%. A large heat tra...
متن کاملBed Voidage and Heat Transfer in Non-Newtonian Liquid-Solid Fluidized Bed
The presence of particles in liquid-solid fluidized beds enhances the bed heat transfer, because the movement of the particles leads to an increased turbulence in the system. Moreover, the violent movement of the particles has a positive effect on fouling of the heat transfer surface. The aim of this investigation was to perform systematic measurements of bed voidage and heat transfer coeff...
متن کاملHeat Transfer Mechanisms in a Gas – Liquid-Solid Fluidized Beds
Three-Phase Fluidized Beds have found an important place in processing technology as Reactors. Gas-Liquid-Solid fluidization is considered in the present paper as operating bed of fluidized solid particles simultaneously with co-current upward flow of a continuous liquid phase and a gaseous phase dispersed in the form of bubbles. In the present study, the experimental work of the author on heat...
متن کاملImproving 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 between solid and interstitial gas are being proposed. In addition, some modifications have been d...
