Parametric identification during recovery of heat transfer boundary conditions

The development of methods for solving inverse heat conduction problems over time becomes more complicated with a variety of batteries transformer of unsteady heat flux by type and variety of structures, thermal and measuring circuits. The parametric identification of differential-difference models is considered, which take into account various nature of the external influence and the processes occurring in the systems of bodies. The solution was carried out in a standard way using the transition matrix of the system state, which allows obtaining the corresponding temperature values at any time from the initial values of the temperature of each part of the body. A method for establishing a trust region during the restoration of heat transfer parameters is considered. A distinctive feature is the general approach to compiling a differential-difference model of heat transfer for various systems of bodies.
