Domain Decomposition Preconditioners for the System Generated by Discontinuous Galerkin Discretization of 2D-3T Heat Conduction Equations

, 2017
In this paper we are concerned with numerical methods for nonlinear timedependent problem coupled by electron, ion and photon temperatures in two dimensions, which is called the 2D-3T heat conduction equations.

Asymptotic behavior for the vorticity equations in dimensions two and three

, 1994
We establish the selfsimilar behavior of the solutions of the two and three dimensional vorticity equations for some classes of initial data. More precisely, any solution v of the two dimensional vorticity equation taking as initial data a finite Radon ...

High Accuracy Spectral Method for the Space-Fractional Diffusion Equations

, 2014
In this paper, a high order accurate spectral method is presented for the space-fractional diffusion equations. Based on Fourier spectral method in space and Chebyshev collocation method in time, three high order accuracy schemes are proposed.

Attractors for a Caginalp Phase-field Model with Singular Potential

Journal of Mathematical Study, 2018
We consider a phase field model based on a generalization of the Maxwell Cattaneo heat conduction law, with a logarithmic nonlinearity, associated with Neumann boundary conditions.

On the Magneto-Heat Coupling Model for Large Power Transformers

, 2017
This paper studies the magneto-heat coupling model which describes iron loss of conductors and energy exchange between magnetic field and Ohmic heat. The temperature influences Maxwell’s equations through the variation of electric conductivity, while ...

Global strong solutions to the time-dependent Ginzburg-Landau model in superconductivity with four new gauges

, 2016
We propose new gauge conditions for the time-dependent GinzburgLandau model in superconductivity. The global existence of unique strong solutions is proved for the initial boundary problem for the timedependent Ginzburg-Landau equations in three space ...

STUDY OF A DOUBLY NONLINEAR HEAT EQUATION WITH NO GROWTH ASSUMPTIONS ON THE PARABOLIC TERM *

A doubly nonlinear equation with no growth assumptions on the parabolic term or on the heat flux is studied. Two existence and comparison results are established under different assumptions on the data.
