## Abstract Recent advances in dense, multiphase, computational fluid dynamics (CFD) have allowed accurate simulation of the gas and particle motion in bubbling and circulating fluidized beds. Since fluidizedโ€bed reactors are used for many chemical processes, a simulation must also be able to accur

The hydrodynamics have been studied in a cold, freely bubbling, pressurized fluidized bed. The bed has a cross-section of 0.2 m;0.3 m and was operated at pressures between 0.1 and 1.6 MPa and at excess gas velocities of 0.2 and 0.6 m/s. The bed material was silica sand with a mean particle diameter

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
