Method of moments formulation of thermal constriction resistance of arbitrary contacts
Abstract
A method of moments formulation is presented for the numerical computation of the steady-state thermal constriction, or spreading, resistance of contacts over which a contact conductance distribution has been specified. The formulation is valid for arbitrarily shaped planar contacts located on isotropic half-spaces. The procedure is applied to the circular and square contacts with uniform contact conductances. The dimensionless results are presented for a practical range of Biot number.
