多级冲击器压强分布计算及实验验证

Calculation and verification of pressure distribution for the cascade impactor

本文以 SPAL 型多级冲击器为例 ,给出了冲击器各级压强分布的理论计算方法 ;设计加工了压强测试装置 ,测量了多级冲击器在不同工作条件各级实际压强 ;并与理论计算值进行对比分析。

method of theoretical calculation for SPAL cascade impactor was presented. Pressure test system was realized to measure the pressure of each stage under different conditions and the measured results were compared with the calculated results .
