本文对二维高超声速楔形流中激波/边界层干扰的某些方面进行了实验研究，而不是平板/臀部结构。这些流动条件只是几何上的二维，因为在再附着流动区观察到斜坡上的热通量的某些展向周期性变化。这些测量基本上是用计算机红外成象系统在马赫数为7.14、单位雷诺数为7.6 × 106 ~ 24 × 106/m的吹风式风洞中进行的。分析了前缘形状（钝度和几何形状）、平板长度和斜面角对分离区、再附着时的平均传热和传热变化的波长的影响。IR结果进行了比较，其他的实验数据，以及半经验的热通量峰值的相关性。
We deal with an experimental investigation carried out to study some aspects of shock/boundary-layer interaction in nominally two-dimensional hypersonic wedge flow, i.e., over flat plate/rump configurations. These flow conditions are two dimensional only geometrically because some spanwise periodic variations of the heat flux over the ramp in the reattaching flow region are observed. The measurements, basically made by means of a computerized infrared (IR) imaging system, have been performed in a blowdown wind tunnel at Mach number equal to 7.14 and unit Reynolds number ranging from 7.6 x 10 6 to 24 X 10 6 /m. The influence of the leading-edge shape (bluntness and geometry), flat plate length, and ramp angle on the separation region, average heat transfer at reattachment, and wavelength of the heat transfer variations has been analyzed. IR results are compared to other experimental data as well as to semiempirical correlations for the heat flux peak.
