Abstract

An inverse geometric heat conduction problem is solved to detect subsurface cavities by using a BEM-based inverse algorithm which relies on the Cauchy condition prescribed at the exposed surface. The temperature of the exposed surface, which is convecting heat with the surroundings, is determined experimentally using an infrared scanner. An initial guess is made for the cavity. A sequence of forward steady state heat conduction problems is solved in an effort to update the cavity geometry by minimizing a residual measuring the difference between actual and computed boundary conditions under the current system configuration. The iterative procedure is automated through
