Abstract

A reflection-type fiber optic probe was used to measure local solid volume fraction in a cylindrical jetting fluidized bed with a conical distributor using three kinds of particles different in sizes. By analyzing the local voidage fluctuations, the jet contours, and the time-averaged solid volume fraction profiles were studied. The jet extension half angle was found to be much lower than those calculated by Merry’s correlation derived for beds with flat distributors. The solid volume fraction measured on the axis increased almost linearly with the distance from the nozzle. In the annulus, it was about one tenth lower than that at the minimum fluidization. The radial solid volume fraction profile in the jet was found to be parabolic.
