Title

Inverse Problems In Heat Transfer With Applications To Detection Of Subsurface Flaws And Cavities

Keywords

Cavity Detection; Heat Transfer; Inverse Problems

Abstract

The inverse geometric problem finds application to nondestructive evaluation of subsurface flaws and cavities. The governing equation, thermophysical properties, initial condition, boundary conditions, and portion of the geometry which is exposed, are all known, however, the subsurface geometry is to be determined using an overspecified Cauchy condition at the exposed surface. The geometry of the cavity(ies) that generated the measured temperature footprint is to be determined. A boundary condition at the cavity side is specified. Successful detection of subsurface cavities by thermal methods for thre solution of the inverse geometric problem is achieved by (1) a steady approach based on a hybrid BEM singularity superposition methodology or (2) a transient approach based on a meshless method/volume of fluid methodology.
