Determination Of The Heat Transfer Coefficient Distribution

In this paper determination of convective heat transfer coefficient distribution method is presented. The method is based on infrared thermography measurements. Investigations were done in the low speed wind tunnel for the air speed range 1-4 m/s. In order to determine convective heat transfer coefficient, PCB (printed circuit board) with the linear heat source has been used (Fig. 1). It has occurred that simple analytical model is sufficient for determination of heat transfer coefficient distribution.
