The similarity of turbulent spots on the surface of a flat plate is shown by means of heat-flux measurements. The use of non-intrusive heatflux gauges makes it possible to track both the developement of single spots and to compare different spots in different experiments. The results proof that assumptions on the similarity of spots can be extended to these flows. Experiments are performed in a Ludwieg tube at intermediate Mach numbers (Ma = 0.33).
