On inverse boundary thermal conductivity problem of recovery of heat fluxes to the boundaries of anisotropic bodies

Abstract

A method for solution of the inverse boundary thermal conductivity problem of recovery of the heat fluxes to the structural components of aircraft fabricated of anisotropic materials is proposed. The method is based on a previously obtained analytical solution of a 2D nonstationary thermal conductivity problem in an anisotropic fin under boundary heat transfer. The method consists in parametric identification and finite element approximation of the dependence of the heat flux on the spatial variable. A regularizing algorithm is developed that permits identification of heat fluxes with large, up to 10%, errors in the experi mental temperature values. The results obtained in numerical experiments are analyzed.

Existence and Uniqueness Theorems in the Inverse Problem of Recovering Surface Fluxes from Pointwise Measurements

“…A particular attention is payed to numerical solving the problems (1)-( 3) and close to them. Most of the methods are based on reducing the problems to optimal control problems and minimization of the corresponding quadratic functionals (see, for instance, [8][9][10][11][12][13][14]). But the problem is that these functionals can have several local minima (see Sect.…”

Influence of Passenger Comfort Requirements on the Interior Layout of Long-Haul Aircraft

“…The development of long-haul aircraft of the Boeing and Airbus families (Figure 1), covers all the many park problems that exist in the World. An evolutionary attempt to overtake these manufacturers is possible only in a situation of using competencies that give a qualitative gain [15][16][17][18][19][20].…”

Investigation of The Influence of High Frequency Electromagnetic Fields on Sorption Processes

“…These layers change the molecular nature of solid surface and serve as a basis to form oil boundary layers whose viscosity exceeds that of oil in the bulk by an order of magnitude and whose thickness is commensurable with porous channel radius in a number of cases. Due to deposition of oil adsorption layers, the cross-section of filtration channels of porous medium is reduced, its penetrability decreases and, as a result, oil recovery of the porous bed drops [1], [2].…”
