A model to determine stresses and friction forces in moving packed beds with interstitial fluid flow has been developed. The scaling parameters are determined from the governing equations. A plane and an axisymmetric bed geometry are studied and the wall stress calculated under uniform one‐dimensional axial flow conditions. The effect of added transverse flow (for example, due to a screen in the wall) is investigated. The present model is an improvement over earlier, one‐dimensional models with capability to include in the stress analysis varying pressure gradients in all directions which may exist in practical moving bed systems.
