摘要
采用二维非结构化网格建立计算模型 ,计算了静止式气波制冷机的二维流场。验证了Coanda效应 ,得到了射流附壁切换的全过程 ;同时计算得到了静止式气波制冷机内部流场的速度、压力分布 ,捕捉到了射流“卷吸”和充排气的掺混现象。根据计算结果 ,对静止式气波制冷机的性能进行了分析 。
The numerical model was set up adopting 2-dimentional nonstructured mesh.The 2-dimentional flow field of static gas wave refrigerator with FLUENT was simulated.The simulation obtains while process of fluidic attachment and switch and distribution of velocity and pressure of flow field.It validates Coanda effect and catches fluidic whirling phenomena.In according to these results the capability of static gas wave refrigerator is detailed analysed.
