题目:  Steady compressible Navier-Stokes-Fourier system

 

摘要: We study weak and variational entropy solutions to the system of partial differential equations in a bounded three-dimensional domain which describes the flow of a compressible single constituent heat conducting gas under the assumption that the pressure behaves like $\varrho^\gamma + \varrho \theta$, where $\varrho$ denotes the density and $\theta$ the thermodynamic temperature. The existence of solutions is achieved for arbitrary $\gamma >1$ without any assumption on the size of the data.

题目: Steady system for compressible heat conducting chemicallyreacting mixture of gases

 

摘要: Based on the technique developped for the steady compressible Navier-Stokes-Fourier system we consider a system of partial differential equations, based on the model developped by V. Giovangigli, which describes the flow of heat conducting compressible mixtures, where the species may be changed due to chemical reactions. We study existence of a solution without any assumption on the size of the data.
