Estimation of the Thermal Contact Conductance From Unsteady Temperature Measurements
Original language description
Thermal contact conductance is an important parameter for describing the heat transfer between two bodies. When two solids are put in contact and heat transfer occurs, a temperature drop is observed at the interface between the solids. This is caused by an imperfect joint, which occurs because the real surfaces are not perfectly smooth and flat. This paper describes an experimental device for the evaluation of the thermal contact conductance, which was designed and fabricated in the Heat Transfer and Fluid Flow Laboratory. This device was built mainly for simulating metal-forming conditions, which include high pressures (up to 360 MPa) and high temperatures (up to 1200 degC) in the contact of two solids. The principle of this investigation is the unsteady measurement of the temperatures of two solids that are put in contact under different conditions. The surface temperature and thermal contact conductance can be calculated from the measured temperatures by an inverse heat-transfer task. The measured temperature history and the calculated values of the thermal contact conductance for pilot tests are presented in this paper.
