✦ Synopsis

This paper examines the small-amplitude free-surface motions on a homogeneously fluidized bed for which the density ratio p//p, << 1, where p! is the fluid density and Ps is the solid density. It is shown that to leading order in p//p,, the surface motions are independent of the dynamics of the bed varying only with the dimensions of the bed and the conditions at uniform fluidization. Also, at leading order, it is found that provided the fluidization remains homogeneous there is a direct analogy between waves on the free surface of a fluidized bed and waves on the free surface of an inviscid liquid (when surface tension is neglected).
