摘要

用一个放射性粒子和两个部分重叠的检测装置对液体流化床中的固体运动进行了分析，并将其分开。粒子速度由两个不同的估计来确定，利用通过区域边界的净通量和两个连续的停留时间之间的停留时间分布确定粒子的弥散系数也随着液体速度的增加而强烈增加。它是。

Mouvement des particules solides en fluidisation liquide solide

Solid motion in liquid fluidized beds has been analysed using a radioactive particle and two detection devices partly superimposed, dividing the be

Particle velocity was determined by two different estimations, using the net flux across a zone frontier and the residence time between two successive

Particle dispersion coefficients, determined from residence time distribution, were also strongly increasing with increasing liquid velocity. It was co
