abstract

Moving beds are present in a number of engineering equipment. Their analyses contribute to improvement of many energy and material production processes. Here, transport equations for flow in a moving bed reactor are presented. Such device is modeled as a saturated porous matrix with a steady speed. Transport equations are time-and-volume averaged and additional form and viscous drags, due to the porous structure, are assumed to be a function of the relative velocity between phases. Turbulence equations reflect their dependence on the speed of the solid substrate. Results show the decay of turbulent kinetic energy levels as the solid speed approaches the speed of the moving fluid.
