GAS-PARTICLE HEAT TRANSFER COEFFICIENTS IN PACKED BEDS AT LOW REYNOLDS NUMBERS

Experimental data for the gas-particle heat transfer coefficient in packed beds at Reynolds numbers between 2 and 100 were determined using a model which takes into account axial dispersion of heat in the gas phase and axial conduction in the solid phase. Beds of copper, lead, and glass were used with particle sizes ranging from 0.0198 to 0.080 inch. Dynamic thermal conductivities of the solid phase in the direction of flow were measured simultaneously. © 1968, American Chemical Society. All rights reserved.
