ABSTRACT

A mathematical formulation of a two-dimensional inverse coefficient-type problem of radiative-conductive heat transfer for parametric identification of thermophysical properties of partially transparent materials is presented. An algorithm for solution of the inverse problem is described. An accuracy of the solution of the inverse problem and its stability to the presence of random errors in the input data is analyzed. The formulation of the problem of optimal planning of temperature measurements for two-dimensional processes of radiative-conductive heat transfer is given; the impact of the parameters of the scheme of experiment on the results of planning is investigated and measurement plans for a series of experimental conditions are given.
