摘要

Solutions to stationary and moving heat sources on a half space are reviewed for red- angular and elliptic contacts. The effects of shape, heat flux distribution, and orientation with respect to the direction of motion are examined. The dimensionless thermal resis- tance is shown to be a weak function of heat source shape if the square root of contact area is used as a characteristic length scale. Simple expressions are developed for cal- culating total thermal resistances of non - circular moving heat sources by combining asymptotic solutions for large and small values of the Peclet number.
