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
