Websis [1] of T5 data has utilized this approach. However, in hypervelocity ﬂow with a cold wall, the principal boundary layer instability mechanism is the predominantly inviscid acoustic or Mack mode [9]. Unlike the viscous instability of low-speed boundary layers, at high speeds the role of viscosity is primarily in determining the mean ﬂow.
