The data from two shock wave turbulent boundary layer interaction experiments are compared. In both experiments a normal shock interacted with a two-dimensional turbulent boundary layer in an uniform flow with a Mach number of 1.4. One test was performed in the Ludwieg Tube of Calspan Corporation and the other are in the NLR supersonic blow-down wind tunnel. The general set up of the experiments and the models used were quite similar. The only differences were model dimensions, unit Reynolds number and type of windtunnel. The comparison includes wall pressure, the initial boundary layer and static pressure normal to the plate. The wall pressure distributions of both experiments, scaled with a reference length which is a function of the Reynolds number, correlate very well. There is no indication of any influence of model characteristics on the supersonic part of the pressure distribution. In the NLR experiment the skin friction was calculated with the aid of Clauser plots whereas in the Calspan experiment the skin friction was measured with skin friction transducers. Using one set of data the results of both techniques are compared. (Author)
