Heat 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 کاملHeat Transfer of Liquid/ Solid Fluidized Beds for Newtonian and Non-Newtonian Fluids
The excellent performance of fluidized bed heat exchangers is due to the interaction between particles and heat transfer surface and to the mixing effects in the viscous sublayer. In this paper, the results of experimental investigations on heat transfer for a wide range of Newtonian and non-Newtonian (shear-thinning power law) fluids are presented. New design equations have been developed ...
متن کاملModelling radiative heat transfer in packed beds
A comprehensive approach for modelling dependent radiative heat transfer in beds of large (geometric range) spherical particles is presented. Such a system of large spheres lies in the dependent range even for large porosities. We show that the dependent properties for a bed of opaque spheres can be obtained from their independent properties by scaling the optical thickness while leaving the al...
متن کاملHeat Transfer in Segregated Fluidized Beds Part 2: Particle Motion and Its Effects on the Heat transfer in the Segregated Fluidized Beds
In our previous paper, particle and temperature segregations in a fluidized bed of binary particle mixtures were experimentally examined, and heat transfer in the segregated fluidized bed was investigated. As the results, it was shown that the temperature segregation results mainly from low heat transfer coefficient through the interface layer, which exists between the flotsam-rich and jetsam-r...
متن کاملEffect of solid conductivity on radiative heat transfer in packed beds
THE SOLUTION of the radiative heat transfer problem in porous media has received considerable attention for a number of years (e.g.. Vortmeyer [I], Tien and Drolen [2], ’ nd Kaviany and Singh [3]). The medium may be considere d as a continuum or as a discrete collection of particles, depending on whether the packing lies in the dependent or independent scattering/absorption range. Independent s...
