The determination of the partial coefficient of heat transfer from air to a drying fluidized mass of silicagel is given. The data obtained can be correlated by means of the equation h = 1.32 (R)"'re. A comparison of the external and internal heat exchange in a fluidized mass is presented.
Local instantaneous temperature signal and time-averaged heat transfer coefficient were measured using a miniature heat transfer probe. The experiments were carried out in the bottom zone of a 5.8 m high, 0.3 m ร 0.5 m rectangular cross-section circulating fluidized bed. The results show that the he
