Three experimental investigations into one-dimensional wave propagation in liquid fluidized beds are reported: dynamic wave velocity measurements under incipient fluidisation conditions confirm the predictions of a theoretical expression that has been successfully applied to fluidization stability studies; continuity wave velocity determinations confirm a long established relationship; and bed collapse experiments on bubbling liquid fluidized beds lead to the evaluation of the dense phase void fraction and bubble hold-up.
