A novel contactless transient method for measuring local values of heat transfer coefficient

Original language description

This paper presents a new non-contact transient method for measuring the heat transfer coefficient. The proposed method is based on measuring the temperature response of the surface temperature to the heat flux irradiating the same surface, which is affected by the heat transfer coefficient on the back of the surface. The theoretical solution of this problem together with the measured experimental data then enables an evaluation to be made of the local value of the heat transfer coefficient and the corresponding integral value. We present the theoretical foundations, a description of the required experimental setup, the methodology for evaluating the heat transfer coefficient, and an error analysis. The results of forced convection inside the tubes and the incident geometry of the impinging jets in comparison with the experimental results from the literature are presented as validation experiments. Very good agreement is demonstrated and the experimental results obtained by the proposed method lie in the standard range of 10%.
