It is shown that with the decrease in size of particles, their velocity at the exit of Laval nozzle increases under the conditions of both the invariable gas parameters and the same Laval nozzle length; the Laval nozzle length increases with the size of p

研究表明，在气流参数和缩放喷管长度不变的情况下，被气流拖曳的颗粒越大，颗粒在缩放喷管出口处的速度就越低；在颗粒加速率相同的情况下，颗粒越大，所需的喷管长度就越长。
