Popis: Thermal characteristics (TC) of new materials, boundary conditions (BC) on the flame walls of burning devices and other thermal parameters can be determined both with help of experimental investigations and using the solutions to inverse heat conduction problems. The problems of such kind correspond to ill-posed (unstable) problems and need the special solution algorithms working. The problems of identification of thermal parameters on the basis of thermal experiments data are interpreted as the problems of optimal control where the coordinates of control vector are distributed discretely in the time parameters (TC), quality function is the discrepancy between calculated and experimental values of temperature presented as quadratic deviation on each time spacing. With the use of burning device as an example BC are obtained on the flame wall (surface temperature, heat flow and heat transfer coefficients) and the TC of wall material while the device is in use are determined.
