| Abstract: | 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. |
