Abstract This paper presents a critical comparison between two recently proposed discontinuous Galerkin methods for the space discretization of the viscous terms of the compressible Navier–Stokes equations. The robustness and accuracy of the two methods has been numerically evaluated by considering simple but well documented classical two‐dimensional test cases, including the flow around the NACA0012 airfoil, the flow along a flat plate and the flow through a turbine nozzle.
