| 摘 要： | 利用数值仿真开展了侧风条件下短舱流动分离等离子体流动控制研究,首先研究了不同侧风条件下短舱流动分离特性,揭示了侧风角度以及速度大小对流动分离的影响规律.随着侧风角度的增加,进气唇口处分离区域不断扩大且进气截面的总压损失更加严重;随着侧风速度的变大,分离区域变化并不明显,进气截面总压损失系数降低.进一步将等离子体激励布置...

| Abstract: | By simplifying the nacelle into a two-dimensional model,the numerical simulation is used to study the plasma flow control of the nacelle flow separation under crosswind conditions.Firstly,the flow separation characteristics of nacelles under different crosswind conditions are studied,and the influence of crosswind angle and velocity on flow separation is clarified.Further,this paper selects typical working conditions to arrange the plasma actuation on the inner surface of the nacelle,and studied the plasma flow control law of nacelle flow separation under different actuation parameters.The results show that the optimal control effect is obtained when multiple excitations are applied simultaneously upstream of the separation starting point,and the average total pressure loss is reduced by 21.3%. |
