| 摘 要： | 对某发动机进气帽罩防冰热载荷的计算方法进行研究。利用FLUENT软件对帽罩周围的流场进行模拟,同时采用FLUENT中的离散相模型计算帽罩周围的水滴运动轨迹,得到帽罩表面的水滴撞击效率;利用数值计算结果及流动换热经验关系式分析帽罩表面的各项热流,获得该发动机帽罩的防冰热载荷。计算中还比较了不同湍流模型对防冰热载荷的影响。

| Abstract: | Calculating methods of anti-icing thermal loads of an engine inlet cowl are investigated.FLUENT software is used to simulate the flow-field of cowl and the trajectories of water droplets are calculated by employing Discrete Phase Model of FLUENT.The local impingement efficiency of water drops is gained with the trajectories.Then the anti-icing thermal loads of cowl is achieved by analyzing the heat fluxes involved in the energy exchange on the surface with the results of numerical investigation and empirical relation formulas.Thermal loads of different turbulence models are also compared. |
