Fluidisation in a pulsed gas flow
Abstract
The effect offlow pulsations on a 4 in dia air-fluidised bed of glass beads has been investigated in the frequency range 1 to 10 Hz. It was found that the beds have a natural frequency which can be calculated approximately from a model which assumes piston-like behaviour. The shape of the air bubbles rising through the bed fluctuates synchronously with the applied pulsations. Tracer studies using helium gas have shown that pulsation can …
