Abstract : A method is presented for the theoretical calculation of the magnitude of thermal contact, caused by the resistance of two rough surfaces under various compressive stresses and degrees of surface finish. At high heat currents the thermal contact resistance is essentially expressed by the distribution of temperatures within the bodies in contact. In spite of this, up to the present time generally adopted views concerning the function of the individual components of thermal contact resistance and their dependence upon various factors are nonexistent; the available research data are not generalized and in several cases are inconsistent. In this study an attempt has been made to determine analitically the magnitude of the contact resistance for various conditions of contact. (Author)
