A methodology is developed to predict a rectangular cavity lying underneath the surface of a plane wall that dissipates heat by convection to the surroundings. This is also the surface whose temperature is scanned. For a prescribed constant heat flux applying on the cavity surface the cavity depth can be predicted by equating the heat in and out of the system. An analytical procedure is developed that permits checking of the assumed cavity wall position based on comparison between the calculated and the measured surface temperatures. The method is also extended to the prediction of holes in a three-dimensional body (parallelepiped). Examples are provided to illustrate applications.
