From studies of annular packed beds wherein the heat flows purely radially, the coefficients of heat transfer on the inner tube surface and the mean effective thermal conductivities of the bed were determined. The inner and outer diameters of the annular packed bed were 22 and70 mm respectively. The wall film coefficients obtained with air flowing axially through the bed were correlated for N/sub ReM/ <600. The coefficients of heat transfer for cylindrical packed beds were correlated, with 0.054 used for values of alpha / sub ucts are BeO / in the range N/sub ReM/ <2,000. An equation was derived, which can be used for the prediction of the wall film coefficient in packed beds. (auth)
