螺旋桨滑流对发动机进气道气动性能的影响
|
摘要
针对螺旋桨/短舱/进气道一体化构型,采用多重参考系(MRF)法和滑移网格非定常法进行了数值模拟研究,实现了螺旋桨/短舱/进气道一体化内外流耦合流场仿真,研究了不同工况下螺旋桨滑流对进气道气动性能的影响,并与无桨构型的进气道性能进行了对比,最后通过数值分析解释了螺旋桨桨盘后总压上升的原因。结果表明:多重参考系法和滑移网格非定常法对进气道出口的时均参数的计算结果吻合较好,多重参考系法可用于螺旋桨及进气道的气动性能参数计算;螺旋桨做功使进气道总压恢复系数增高,螺旋桨转速越大,总压恢复系数的增量就越大,且螺旋桨滑流使进气道出口畸变指数明显增大;通过数值分析推导的桨盘前后总压关系公式与仿真结果的误差均在3%以内。
For the integrated configuration of propeller/nacelle/intake,numerical simulation was carried out by using multiple reference frame(MRF)method and slip grid unsteady method,and the coupled flow field simulation of the internal and external flows of propeller/nacelle/intake integrated was realized.The aerodynamic performance influence of propeller slipstream on the intake under different working conditions was researched,and compared with the performance of the intake without the paddle configuration.Finally,the reason for the increase of the total pressure after the propeller paddle was explained by numerical analysis.The results show that the result of the multiple reference frame method is consistent with the time-average parameters result of the slip grid unsteady method,the multiple reference system method can be used to calculate the aerodynamic performance parameters of the propeller and the intake port.The work of the propeller increases the total pressure recovery coefficient of the intake port.The greater propeller speed means the greater increment of the total pressure recovery coefficient,and the propeller slipstream significantly increases the inlet port distortion index.The formula of the relationship between the total pressures before and after the paddle has been derived by numerical analysis,and compared with the simulated value,with the error within 3%.
