A description is given of the apparatus used in order to measure the velocity of sound in liquid hydrogen and helium with the optical method, indicated by D e b y e and by B i q u a r d. The light beam enters the cryostat at the top and passes an evacuated glass tube, shut off at the bottom by a pla
Three experimental investigations into one-dimensional wave propagation in liquid fluid&d beds are reported: dynamic wave velocity measurements under incipient fluidisation conditions confirm the predictions of a theoretical expression that has been successfully apdlied to fluidization stability stu
