Abstact The paper describes an experimental investigation of convective heat transfer in case of planar air jet impinging a hot V-shaped surface. In such a flow configuration the jet experiences a flapping behaviour leading to a stable self-sustained periodic flow characterized by a constant Strouhal number. To determine the timedependent mapping of the convective heat transfer coefficient infrared thermography is used in connection with a very thin metallic-foil of low heat capacity for the
