Assessment of various methods in solving inverse heat conduction problems

Abstract

In an inverse heat conduction problem (IHCP), the boundary conditions, initial conditions, or thermo-physical properties of material are not fully specified, and they are determined from measured internal temperature profiles. The challenge is that the effect of changes in boundary conditions are normally damped or lagged, ie the varying magnitude of the interior temperature profile lags behind the changes in boundary conditions and is generally of lesser magnitude.
