Abstract : A test technique using an axisymmetric model was successfully developed in order to study the effect of a small amount of cross flow on two dimensional laminar shock wave boundary layer interactions at a Mach number of 2.25. In the absence of cross flow the experimental results were in excellent agreement with Horton's theory developed for axisymmetric bodies. The effect of cross flow was to reduce the static pressures throughout the complete interaction region. It was also shown that two dimensional models with an aspect ratio of 2.5 could be used free of side effects to study the influence of a small amount of cross flow. (Author)
