粉粒体流态化工况的简捷计算

摘要

In calculation of solid particle critical velocity, lfuidization velocity and settling velocity (single particle freely settles in unlimited space and particle group settles with resistance in limited space), A. H. Pulanofsky’s equation was recommended by the author. In this way, several equations used in conditions ofε=0.4~1.0 respectively can be replaced by one equation.%推荐用A.H.普拉诺夫斯基通用公式计算流态化工程中粉粒体临界速度、流态化速度和沉降速度（单一粒子在无限空间中自由沉降和粒子群在有限空间中受阻沉降）。用一个计算式取代计算床层空隙率ε=0.4~1的M.李伐、O.M.托杰斯、司托克斯、阿莱茵、牛顿公式，使工程计算简单化。
