  Nonlinear entropy stability analysis is used to derive entropy stable no-slip
wall boundary conditions for the Eulerian model proposed by Sv\"{a}rd (Physica
A: Statistical Mechanics and its Applications, 2018). and its spatial
discretization based on entropy stable collocated discontinuous Galerkin
operators with the summation-by-parts property for unstructured grids. A set of
viscous test cases of increasing complexity are simulated using both the
Eulerian and the classic compressible Navier-Stokes models. The numerical
results obtained with the two models are compared, and differences and
similarities are then highlighted.
