Abstract

This communication describes a numerical study on collisional solid's pressure influence upon the hydrodynamics of the gas-solid flow in a 2D riser using a traditional two-fluid formulation. It is seen that the solid's pressure exerts considerable influence on the transient flow behavior, and should not be disregarded in project or study of circulating fluidized beds (CFB) systems. It was made clear the necessity for a criterious use of the available correlations for the collisional solid's pressure as inserted into the traditional two-fluid model. (AU)
