为了研究壁面温度对来流脉冲扰动下高超音速流动的影响，采用高阶有限差分格式数值模拟了绝热壁和3种等温壁条件下高超音速来流扰动非定常流场，并应用Fourier频谱分析讨论了不同壁温条件下扰动波在边界层的发展过程。结果表明，壁温对脉冲波作用下流场的影响主要集中在边界层，而对远离壁面的流场影响较小，壁温不同表面密度和摩擦系数分布有明显的差异。同时，壁温条件对脉冲波作用下的高超音速边界层扰动波的发展有着显著地影响。%In order to research the effects of wall temperature on the hypersonic flow under the action of pulse dis-turbance, the unsteady flow field on hypersonic stream disturbance under three isothermal walls and adiabatic wall was simulated by the high-order finite difference format value. In addition, Fourier frequency spectral analysis ( FF-SA) was applied for discussing the development process of disturbance waves in the boundary layer under different wall temperature conditions. The results show that, the effects of wall temperature on the flow field under the action of pulse wave are mainly concentrated in the boundary layer, while it has a little effect on the flow field far away from the wall. The surface friction factor and density have apparent differences at different wall temperatures. Fur-thermore, wall temperature conditions have a significant influence on the development of disturbance waves in the hypersonic boundary layer under the action of pulse wave.
