Journal ArticleDOI
Solution of a stationary inverse heat conduction problem by means of Trefftz non-continuous method
TL;DR: In this paper, the non-continuous FEM with Trefftz base functions (FEMT) applied to direct and inverse problem of heat conduction equation has been presented.
Journal ArticleDOI
Solution of the stationary 2D inverse heat conduction problem by Treffetz method
TL;DR: In this article, a solution of Laplace equation with the use of FEM harmonic basic functions is presented, which is aimed at presenting an approximate solution based on possibly large finite element.
Journal ArticleDOI
Regularization of the inverse heat conduction problem by the discrete Fourier transform
TL;DR: In this article, two methods of solving the inverse heat conduction problem with employment of the discrete Fournier transform are presented, which operate similarly to the SVD algorithm and consist in reducing the number of components of the DFT which are taken into account to determine the solution to the inverse problem.
Journal ArticleDOI
Solution of the inverse heat conduction problem described by the Poisson equation for a cooled gas-turbine blade
TL;DR: In this paper, a method of solving the inverse problems of heat conduction, consisting in solving the Poisson equation for simply connected region instead of the Laplace equation for a multiply connected one, like a gas-turbine blade provided with cooling channels, is presented.
Journal ArticleDOI
Physical regularization for inverse problems of stationary heat conduction
TL;DR: In this paper, the physical foundation of a functional for solving discontinuous stationary heat conduction problems with a kind of regularization parameter has been presented, and the non-continuous FEM with Trefftz base functions and a wide range of the regularisation parameter values has been applied to solving direct and inverse problem of linear heat convection.
