We study steady flow of a compressible heat conducting viscous fluid in a bounded two-dimensional domain, described by the Navier-Stokes-Fourier system. We assume that the pressure is given by the constitutive equation $p(\rho ,\theta )\sim {\rho }^{\gamma }+\rho \theta$, where $\rho$ is the density and $\theta$ is the temperature. For $\gamma >2$, we prove existence of a weak solution to these equations without any assumption on the smallness of the data. The proof uses special approximation of the original problem, which guarantees the pointwise boundedness of the...
