摘要
本文以M2129进气道为研究对象,设计了7种不同微喷气控制方法,通过分析轴对称面轴向速度云图、出口截面总压恢复系数云图、二维速度流线图及总压恢复系数值的变化,研究了喷气位置、喷气角度、喷气量和喷气孔数等因素对S形进气道流场及性能的影响。结果表明:喷气位置对于减小进气道的分离、总压损失和畸变起决定性作用;喷气角度和喷气量与喷气位置的耦合作用才会对微喷气控制效果产生明显的影响;而喷气孔孔数在一定范围内也影响进气道的性能。
The paper designed seven groups of micro-jet control method to study the jet location, jet angle, the jet flow and the number of jet holes effect on the flowfield and performance of M2129 intake. The simulation results show that： the jet location plays an impor- tant role in reducing the intake separation bubble, the total pressure loss and the outlet distortion; the jet angle and the jet flow coupled with the jet location have obvious effect on the micro-jet control results; within a certain range, the number of jet holes also affect the performance of the intake.
