Popis:	An infrared technique is used to investigate the temperature field on the surface of heated walls in turbulent boundary layers. This method is based on measurement of local temperatures on the surface of a heated film, fixed on a solid frame, by means of infrared thermography. The behaviour of such a sensor is considered in connection with the variation of flow characteristics, film geometric parameters, physical properties of its material, etc. The advantages of the present method are illustrated in its application in the analysis of temperature fields on the surface of a wall in a turbulent boundary layer, under various flow conditions.
