Abstract
A numerical analysis is formulated and used to determine the transient temperature fields associated with Joule heating of a cooled stationary electrical contact. The contact is treated as a hemisphere. The field equations are developed using complex variables and conformal transforms, and the resulting equations are solved using finite differences.
Contours of constant temperature are given that show a maximum temperature located very close to the center of the contact patch; this qualitatively agrees with earlier findings of Holm.
