Abstract:
The modified packet model for heat transfer between a gas-fluidized bed and an immersed surface is presented. In contrast to the model of Mickley and Fairbanks, allowance was made for the effective gap heat resistance between the packet of particles and surface (the contact thermal resistance Rk) and for the heat transferred directly by convection through the gas filtering through the particles and between the particles and the immersed object. The convective contribution towards the maximum heat transfer coefficient is found to increase with increasing particle size. This model readily explains the effect of particle moisture content, shape of the immersed body and other factors on bed to immersed body heat transfer. Radiant heat transfer effects are discussed. © 1973.
