説明
Bed expansion of the liquid-solids fluidized bed was analyzed by use of the concept of statistical mechanics.<BR>Assuming that cells composed of a combination of both individual particles and local fluid are in stochastic motion, the particle velocity distribution function is given in the form of an exponential function. An experimental determination of the function was made from measurements of the bed-expansion curve.<BR>As a result, the exponential distribution function P(Usi)dUsi is given as follows : <BR>p (Usi) dUsi=1/Us-Uscexp (-Usi-Usc/Us-Usc) dUsi<BR>where Usi is instantaneous particle velocity and Us is average particle velocity. Also, it is indicated that minimum average particle velocity Usc can be estimated by a single term of terminal velocity.
