Development of a thermal method for measuring the transition velocities of fluidized binary mixtures

摘要

This experimental study of the transition velocities of binary mixtures was developed for 5 harmonic mean diameters ranging from 282.5 #mu#m to 1800 #mu#m. The proposed thermal method (measurement of heat transfer coefficient versus gas velocity at 2 depths from the grid, and analysis of the plots) can be a good alternative way to Richardson's method to determine the complete fluidization velocity. It is even more sensitive for determinig the imcipient fluidization velocity.
