摘要
考虑粉粒体积分率对气粉两相流的影响，作者曾经建立了收缩-扩张喷嘴中气粉流的数学模型，还采用了压强检验法，来确定喷嘴的临界截面，由此对超声速气粉流的行为作了数值计算．本文将介绍研究收缩-扩张喷嘴中气粉流行为的实验装置，并将根据实验结果与数值计算结果的对比，来验证本数学模型和压强检验法的合理性．
Considering the influence of particle volume fraction on two-phase flow, a math ematical model for describing the behavior of gas-particle flow passing through a convergent divergent nozzle was developed. Using the pressure check method, the critical cross-section of nozzle was determined and the behavior for supersonic gas-particle flow was calculated. The experimental set-up for studying gas-particle flow in a convergent-divergent nozzle is introduced.Through the comparison between the experimental and calculated results, the rationality of the mathematical model and pressuxe check method is verified.
