摘　　要：针对可以处理高温高压环境下可压缩空气的无滤网式引气除尘器,利用数值模拟的方法,比较了Realizable湍流模型和RSM湍流模型下引气除尘器内部的切向速度分布特性。通过分析内部气体流场和颗粒相流场的特征,研究了飞机环控系统无滤网式过滤器的除尘机理。同时,研究了叶片参数,比如叶片数量、叶片回转角和叶片通道距离对飞机环境控制系统引气除尘器性能的影响,还研究了进口流量对引气除尘器性能的影响。To compressed air can be treated under high temperature and pressure without filter air entraining dust collector, by using the numerical simulation method, compared the Realizable turbulence model and the RSM turbulence model of air entraining precipitator internal tangential velocity distribution characteristics. By analyzing the characteristics of flow field and particle internal gas phase flow field, studies the mechanism of dust removal of aircraft environmental control system without net type filter. At the same time, of blade parameters, such as the effect of blade number, blade rotating angle and blade passage distance of aircraft environmental control system of air entraining precipitator performance, also studied the effects of inlet flow on the air entraining precipitator performance.
