Thermal Contact Resistance of Wavy Surfaces (RESEARCH NOTE)

In this paper, the method of determining thermal contact resistance of wavy surfaces is discussed exactly. For determining the thermal contact resistance of real contacts, a new method has been presented. In this method, assuming a regular sinusoidal surface profile, the real contact area in terms of applied forces has been determined. Then thermal contact resistance has been calculated. Testing ۶ kinds of insulator’s combinations with wavy surfaces has approved the reliability of the analysis. The results of experiments and analysis had good agreement with each other.
