The pressure drop correlation: {A figure is presented} proposed on the basis of theoretical considerations, is compared with published experimental results obtained from high voidage fixed beds of spheres and is shown to represent a significant improvement over the established Ergun equation. It is used to produce drag coefficient correlations for individual particles in the bed which in turn yield a general and fully predictive expression for the drag force on a particle in a fluidized suspension.
