The experimental investigation of the generation of instable Goertler vortices during the dissipation process of free stream disturbances on non-uniform surface was conducted. The experiments were performed in controlled disturbance conditions. It was demonstrated that the receptivity mechanism used is relatively weak. However, due to application of the high-precision experimental technique, the Goertler vortices excited in the boundary layer can be measured reliably by a hot-wire anemometer. A detailed information required for determination of quantitative characteristics of the boundary-layer receptivity problem under study is obtained.
