Numerical Simulation and Optimization for Variable Geometry Inlet of TBCC Under Non-uniform Incoming Flow

  • 摘要: 为提高内并联式涡轮基组合循环发动机进气道的工作特性,设计了一种带多级楔板的扩压段二维进气道.采用数值模拟方法研究了非均匀来流对其流场特性及性能参数的影响,并与非均匀来流对常规型进气道特性的影响进行了比较.模拟结果表明:采用带多级楔板的扩压段二维进气道性能受非均匀来流影响更小,扩压段内出口流场有明显的提升;模态转换状态下,与常规型进气道相比,进气道出口总压恢复系数平均增大10%,总压畸变指数平均降低15%左右,冲压出口马赫数均小于0.41,出口温升比降低.从而使得发动机推力增加,耗油率降低,改善了TBCC发动机的性能.
