Abstract

Abstract

A mathematical model of three-dimensional steady-state heat conduction in the contact surface between two coaxial cylindrical layers is developed and an analysed solution of thermal resistance of contact is obtained.It is shown that the heat conduction in the rugosity unit cell may be reduced to an arrangement of the fluid thermal resistance,the rugosity thermal resistance and the constriction thermal resistance.
