Electrical conductivity probes were used to measure the radial distributions of solids holdup and liquid velocity in a liquid-solid circulating fluidized bed. These distributions are found to be non-uniform, unlike those in a non-circulating bed. The effects of superficial liquid velocity and partic
In this paper it is shown that the gas #ow pattern in the dense bottom-bed of circulating #uidized beds, operated with Geldart-B type of solids, exhibits three di!erent types of dynamic behavior, dependent on the width of the riser and on the aspect ratio of the dense bottom-bed. These types of dyna
Abstraet--A new approach to the modelling of gross gas-solids flow through the riser in a circulating fluidized-bed system is proposed in this paper. This approach differs from the previous ones, which are found to be theoretically incorrect based on a fundamental analysis of the riser process hydro
