本文利用FLUENT软件对圆柱型喷嘴的自由射流流场进行了仿真研究,分析了喷嘴轴线上压力及速度的变化原因以及干冰颗粒的运动情况,发现膨胀波和斜激波的交替出现是影响干冰颗粒速度的变化的最主要原因。结合模拟干冰清洗的碰撞过程的仿真结果,分析了板激波出现的原因,为确定干冰清洗最优靶距提供理论依据。

The free jet flow field of cylindrical nozzle was simulated with FLUENT software.The causes of pressure and velocity variation on the nozzle axis and the movement of dry ice particles were analyzed.The alternation of expansion wave and oblique shock wave is the most important factor affecting the velocity variation of dry ice particles.Combined with the simulation of dry ice cleaning process,the causes of plate shock wave are analyzed,and the theoretical basis for determining ...
