摘要
以内埋式通风口为研究对象,应用混合化网格,建立发动机短舱模型。采用SIMPLE算法,求解了流动和换热控制方程。对舱内流动和换热问题进行研究,得到了地面开车、地面滑行,以及不同高度、不同马赫数条件下动力装置舱内流场和温度场,解决了内埋式通风口进口流量无法测量的难题,为新型动力装置冷却通风系统的研究具有指导意义。
Based on inter vent scoop, model of engine model is set up using the mix-grids. The flow and heat transfer control equations were solved by the SIMPLE algorithm. The flow and heat transfer question were simulated and the flow and temperature field were received in different conditions of ground test, ground slide, some altitudes and some Mach number. The problem of measuring the inter vent scoop flow flux is settled, which is helpful for investigation of nacelle cooling and ventilation system.
