WE HAVE the following comments to make in reply to the communication by Mr. Godard and Professor Richardson: I. Equation (I) in our paper [ I] refers to a bubbling fluidised bed with constant voidage fraction between bubbles. Most liquid-solid systems are non-bubbling and of course fall outside the

Based on the observed pattern of coalescence of bubble pairs in vertical alignment in a two-dimensional bed, a theory is developed which describes how bubble size and frequency changes with height in a gas fluidised bed. It is confirmed by comparison with the reported data from 10 separate investiga
Well dellned spontaneous oscillations can occur in a gas-fluidised bed with a low resistance support and a large gas space beneath the support. Measurements of the instantaneous pressure drop as a function of time have been carried out in a 10 cm dia. bed with gas space volumes between 11 and 191. A
