Kostikov A. Identification and optimization of the geometrical parameters of the objects of power engineering and radio electronics by solving the inverse heat conduction problems

The subject of the study is thermal processes in the objects of power engineering and radio electronics, the geometrical parameters of that objects. The purpose is elaboration of the general universal methodological approach to solve geometrical inverse heat conduction problems (IHCPs). Methods of study are methods of the theory of heat-and-mass exchange, mathematical physics, optimization, mathematical statistics, computer simulation and programming. Theoretical and practical results consist of classification of geometrical IHCPs; general universal methodological approach to their solving; procedures of solving the several classes of geometrical IHCPs; procedure of thermal design of electronics with liquid cooling; the recommendations regard to safety handling of dry storage of spent fuel; design and recommendations regard to using geothermal energy and heat of waste coal piles as nonconventional power sources; mathematical models, algorithms and software for simulation of thermal processes taking place in abovementioned technical objects. Novelty: as a result of conducted investigations the vital scientific problem of elaboration of complex methodology of solving the geometrical IHCPs is solved. It allow to determine the geometrical parameters of technical objects during their diagnostics or designing. The realization level: developed methods, software and recommendations are used in the research, practical and training practice, which is confirmed by seven acts of introduction and certificate of usage. Field of use is engineering thermal physics and industrial heat-and-power engineering.
