Application of inverse problem methods to heat transfer methodology and identification of radiative-conductive mathematical models for composite materials

Exploitable results

The main scientific results achieved are: the analysis of requirements and application fields for boundary inverse heat transfer problems;the statement of the problem of identification for heat transfer processes in semi-transparent composite materials based on the solution of inverse heat transfer problems; the development of the method, algorithm and computer code for identification of heat transfer processes in solids based on the solution of inverse heat transfer problems; the development of the method and algorithm for identification of radiative)conduction heat transfer processes in solids based on the solution of inverse heat transfer problems; the development of the computer code for identification of heat transfer processes in solids based on the solution of inverse heat transfer problems (estimating heat fluxes);the participation of 7 Russian scientists (involved in INTAS project) at the 2nd International Conference on Inverse Problems in Engineering (France, 1996) with presentation of algorithms and computers' codes for inverse problems solving; carrying out of experimental investigations on laboratory installations and test stands to check mathematical models of RCHT and identification of unknown heat transfer parameters; numerical analysis of computational effectiveness and error analysis of algorithms for research of characteristics of Heat Transfer based on the solution of inverse heat transfer problems and modern computer technology ;the development of an algorithm and computer code for non-stationar, non-linear and multi-dimensional heat-and-mass transfer processes running in the elements of the structures, this sufficiently increasing the accuracy and truth of the results of investigations; the increasing of the information efficiency of experiments and tests; to provide a possibility to conduct them in the conditions approximate to the maximum to the full-scale conditions; the reducing largely of the volume of necessary experimental investigations and tests, and consequently, the expenses in resources and time for the development of technology prototypes; the participation of one French and two German scientists (involved in the INTAS project) at the 3rd International Conference on Dynamic Systems Identification and Inverse Problems (Russia, 1996) with presentation of algorithms for inverse problems solving; the conception for the system of computational and experimental research of characteristics of Heat Transfer based on the solution of heat transfer problems and modern computer technology; such system can be created in case of additional foundation can be used in different branches of industry.
