| 摘 要： | 分析制冷系统中几种常用的旋流式气液分离器压降模型的计算方法,并对旋流分离器的升气管压降计算模型进行了计算对比.分析发现:对于一个光滑器壁的旋流分离器在低入口浓度下的压降,使用简单的经验压降模型是足够的;但旋流分离器器壁粗糙时,则使用Barth模型和Muschelknautz 模型更合适;而 Stairmand 模型对摩...

| Abstract: | The computational methods on several kinds of pressure drop models for gas-liquid cyclone separator in refrigeration system were analysed.And different pressure-drop models of pneumatic tube concerning several types of cyclone separator were calculated and verified.The result shows that for a smooth wall cyclone separator' pressure drop,at the low concentration,the simple pressure drop model was sufficient.But when the wall is rough,it was better to use Barth and Muschelknautz model;And the Stairmand model ... |
