摘要：

The conduction mode of heat transfer in packed beds subject to flowing gases has been studied analytically. The analysis is based on the more realistic assumption of a finite contact spot between the spheres in the bed, the dimensions of which may be obtained from the Hertzian elasticity theory, rather than the usual assumption of a point contact. Moreover, the convective effects of the flowing gas were also incorporated in the analysis as boundary conditions. The effect of parameters such as contact spot dimensions, packing geometry, Biot modulus (convective effects), and radiation on the conduction mode have also been examined. © 1979, American Chemical Society.
