摘要
摘要 对自由流马赫数 M = 2.5 时钝前缘平板上 N 波形式的弱冲击波与超音速层流边界层的相互作用进行了数值研究。数值结果与已知实验数据进行了比较。讨论了 N 波和前缘钝化对层流-湍流过渡过程的综合影响。
Numerical Simulation of the Interaction between Weak Shock Waves and Supersonic Boundary Layer on a Flat Plate with the Blunt Leading Edge
The interaction of weak shock waves in form of an N-wave with the supersonic laminar boundary layer on a flat plate with blunt leading edge at the free-stream Mach number M = 2.5 is numerically studied. The numerical results are compared with known experimental data. The combined influence of the N-wave and the leading edge bluntness on the laminar-turbulent transition process is discussed.
