阿蒙森已经完全解决了球形颗粒床的热或物质传递问题。在本文中，我们考虑的修改时，必须在稳定状态下的解决方案，床可能由不规则形状的颗粒。考虑一级反应的扩散限制的情况下，它表明，所有形状的结果将躺在一起，如果采取的颗粒的特征尺寸bevp/sx，其体积的比，其外表面积。
The problem of heat or matter transfer for a bed of spherical particles has been fully solved by Amundson. In this paper we consider the modifications which must be made in steady state solution when the bed may consist of irregularly shaped particles. Considering the case of diffusion limitation of a first order reaction it is shown that the results for all shapes will lie close together if the characteristic dimension of the particle is taken to bevp/sx, the ratio of its volume to its external surface area.
