Knowledge of bed expansions is important in the design and operation of gas-solid fluidized beds. This paper presents a study on the estimation of expanded bed height in a large three-dimensional gas-fluidized bed with a square section of 0)61;0)61 m. All experiments were performed at the freely bub

A~traet--Tbe density and flux of particles in the freeboard of a freely bubbling fluidized bed is a function of the size, aspect ratio and frequency of bubbles erupting at the surface of the dense bed. To predict the velocity and amount of material thrown into the freeboard, a previous model for the
