Compact Analytical Models for Effective Thermal Conductivity of Rough Spheroid Packed Beds
New compact analytical models for predicting the effective thermal conductivity of regularly packed beds of rough spheres immersed in a stagnant gas are developed. Existing models do not consider either the influence of the spheres roughness or the rarefaction of the interstitial gas on the conductivity of the beds. Contact mechanics and thermal analyses are performed for uniform size spheres p...
متن کاملFlow through Packed Beds and Fluidized Beds
Chemical engineering operations commonly involve the use of packed and fluidized beds. These are devices in which a large surface area for contact between a liquid and a gas (absorption, distillation) or a solid and a gas or liquid (adsorption, catalysis) is obtained for achieving rapid mass and heat transfer, and particularly in the case of fluidized beds, catalytic chemical reactions. You wil...
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...
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 کاملNumerical Simulation of Heat Transfer in Packed Beds by Two Population Thermal Lattice Boltzmann Method
The Lattice Boltzmann Method (LBM) was used for simulation of a gas flow and conjugate heat transfer in fixed packed beds with solid particles inside. D2Q9 version of the Factorized Central Moment (FCMLBM) is used for a gas flow computation. Heating transfer in the bed is described by second distribution function set and multiple relaxation time lattice Boltzmann method (DDF MRT LBM) is used. N...
