为研究固相颗粒在液相中的悬浮机理，在二维模拟反应器中针对平底反应器和截头锥底反应器两种类型、三种不同角落点的颗粒悬浮情况进行了实验．建立了一套电化学测量一信号转换一微机采样系统，测量了角落点附近流场的底面剪切速率．在综合理论与实验的基础上，讨论了随流场改
In order to study the suspension mechanism of solid particles in the liquid phase, experiments were carried out in two-dimensional simulation reactor for the particle suspension at two different types of flat bottom reactor and truncated cone bottom reactor. A set of electrochemical measurement-signal-conversion-microcomputer sampling system was set up to measure the bottom shear rate of the flow field near the corner point. On the basis of comprehensive theory and experiment, we discuss the change with the flow field
