Determination of Conductivity in a Heat Equation
We consider the problem of determining the conductivity in a heat equation from overspecified non-smooth data. It is an ill-posed inverse problem. We apply a regularization approach to define and construct a stable approximate solution. We also conduct numerical simulation to demonstrate the accuracy of our approximation.
متن کاملTransient Heat Diffusion with Temperature-Dependent Conductivity and Time-Dependent Heat Transfer Coefficient
Lie point symmetry analysis is performed for an unsteady nonlinear heat diffusion problem modeling thermal energy storage in a medium with a temperature-dependent power law thermal conductivity and subjected to a convective heat transfer to the surrounding environment at the boundary through a variable heat transfer coefficient. Large symmetry groups are admitted even for special choices of the...
متن کاملHeat flux in a vibrated granular gas: the diffusive heat conductivity coefficient
The transport coefficient coupling heat flux and density gradient in a granular gas is measured by taking advantage of the existence of a minimum in the temperature profile of an open vibrated granular medium. This temperature inversion is closely related to the existence of the new transport coefficient. Particle simulations using the Direct Simulation Monte Carlo method will be used to comput...
متن کاملDirect Solution of 2D Heat Transfer Problems in Frequency Domain with Dynamic Boundary Conditions
To design a good control system, it is essential to have accurate dynamic models of the system being controlled. Frequency response techniques can be used to develop such dynamic models. In this paper, a new approach for direct solution of the frequency response of 2D heat transfer problems with nonlinear source terms and dynamic boundary conditions is proposed. Three typical boundary condition...
متن کاملAverage Heat Transfer Coefficient in Rectangular Ducts with Baffle Blockages
An experimental investigation was conducted to study the average and the fully-developed heat (mass) transfer coefficients in a rectangular smooth duct and a duct with repeated-baffle blockages. The focus of attention in this work is the conventional correlation Nu / Nufd 1 + C / ( X / D ) for the average heat transfer coefficient. It was shown that for relatively short ducts, the coefficient C...
