摘要: 该文利用人工可压逼近方法来研究不可压的Navier-Stokes-Fourier方程的逼近问题.首先引进扰动的可压Navier-Stokes-Fourier方程族,当➝0+时,其逼近不可压的Navier-Stokes-Fourier方程.其次给出了扰动的可压Navier-Stokes-Fourier方程解的存在性并证明其收敛到不可压的Navier-Stokes-Fourier方程的解.

Abstract: This paper investigates the approximation of the incompressible Navier-Stokes-Fourier system by the artificial compressibility method. We introduce a family of perturbed compressible Navier-Stokes-Fourier system, which approximate the incompressible Navier-Stokes-Fourier system as ➝0+. Then we prove the existence and the convergence of solutions for the perturbed compressible Navier-Stokes-Fourier system to the solutions of the incompressible Navier-Stokes-Fourier system.

Key words: Artificial compressibility method, Navier-Stokes-Fourier system
