We consider a model of thermal dissipation for a Stefan}Boltzmann model of viscous and reactive gas in a bounded interval. We prove the existence of a global-in-time solution, and we give the asymptotic behaviour for the corresponding Dirichlet problem.

โฆ Synopsis
Viscous sintering of a porous ball with various initial distributions of porosity versus radius is considered. For the solution of the corresponding boundary-value problems of the evolution of porosity and ยฏow velocity ยฎelds during sintering, the numerical algorithms based on the dierential quadrature method (DQM) and an arbitrary EulerianยฑLagrangian version of the ยฎnite element method (FEM) (the permeable element method) are elaborated. A comparative analysis of the calculation results is carried out. The question of the inยฏuence of non-uniformity of porosity distribution on the localization of densiยฎcation is discussed.
