Identification of thermal characteristics of super-hard synthetic materials by means of inverse heat transfer problem approach

摘要

The Adaptive Iterative FIlter method has been proposed for the determination of the thermophysical characteristics of solid materials by means of Inverse heat STransfer Problems solution. Hwever, the inverse problems are ill-posed problms in sense of existence, uniqueness and stability and, as such, in general case they do not have a universal solution. Therefore, on the stage preceding the actual solving real inverse problem, the simulating inverse analysis should be done. This analysis,which includes the solution of the methodical inverse problem, is very desired or sometimes even required obtaining stable and precise results of identification. The suitable numerical algorithms of Adaptive Iterative Filter are used for the simultaneous identification of the thermophysical characteristics of super-hard synthetic polycrystalline materials that were identified as a function of the temperature.
