Abstract: Series expressions for transient constriction resistances are presented for two elemental flux channel geometries: infinite strip contact bounded by adiabats and a circular spot contact on an insulated cylinder. Both flux channels are semi-infinite in the direction of heat flow and the contacts are heated by a uniform flux source. The resistances were derived from the temperature distributions which were determined by solving the heat equation with Laplace transforms. Results are given in tabular and graphical form, and show that the resistances reach the known steady state values. It is also shown that the resistances approach the half space solutions for small constriction ratios.
