Abstract (en)
[origin: WO03104769A2] The invention relates to a method and a device for determining the aerodynamic wall shear stress in a measuring zone (1a) on the surface of a body (K), around which a flow medium flows. A measuring layer (S) is arranged on said surface in the vicinity of the measuring zone (1a), said measuring layer being thermally transparent in a first IR-wavelength range and absorbing heat in a second IR wavelength range, in order to radiometrically measure the temperature (TW) on the surface of the measuring layer (S) and the temperature (Ts) on the surface (F1) that is covered by the measuring layer (S), using an infra-red camera measuring system (2), whereby the measuring layer (S) is in addition sensitive to pressure.
