Studies of momentum, heat and mass transfer on semifluidized beds in circular and non- circular cross sections have been gaining considerable attention in the fight of their industrial applications. A critical literature review has been made with regard to studies of pressure drops with some mechanical and dynamic characteristics across both liquid-solid and gas-solid semifluidized beds. Generalized correlation available in the fields of momentum, heat and mass transfer provide a reliable basis to design, operate and apply in practice the semifluidized beds with greater confidence. The present paper summarizes the work done earlier in the areas of semifluidization with two phase fluid solid contact. Attention has also been focused on the present status of industrial importance of semitluidized beds. It is proposed that more extensive work not only on two phases but also on three phase semifluidization may be under taken to meet the present industrial requirements.
