✦ Synopsis

The Goertler instability of a hypersonic boundary layer A and its influence on the wall heat transfer are experimentally ana-2 lyzed. Measurements, made in a wind tunnel by means of a p computerized infrared (IR) imaging system, refer to the flow over 51 two-dimensional concave walls. Wall temperature maps (that are a interpreted as surface flow visualizations) and spanwise heat transfer 6fluctuations are presented. Measured vortices wavelengths are corre-0 lated to non-dimensional parameters and compared with numerical
