Abstract
The paper presents an analysis of the periodic temperature distributio n in a semi-infinite medium with continuous inhomogeneity in thermal c onductivity, and evaluates its effect on the heat flux at the surface. This analysis has been used to calculate an effective heat transfer c oefficient between the air and the ground. For two inhomogeneous therm al conductivity profiles (linearly decreasing and exponentially increa sing), the inhomogeneity factor for the effective heat transfer coeffi cient has been determined.
