Modeling and analysis of inverse heat transfer problems for containment wall applications

Mathematical formulation of several inverse heat conduction problems is done. Method of minimization of least squares accelerated by Levenberg-Marquardt algorithm is used for the inverse solution. Inverse codes prepared are tested using simulated measurements. Experimental setup is also being prepared for checking validity of the inverse algorithm under practical boundary conditions. This method can be applied to find the local temperature or heat flux on the containment walls of nuclear reactor. This method of finding temperature/heat flux is non-intrusive and hence more attractive than conventional thermal sensors. (author)
