Large-eddy simulation provides a feasible route to solutions of higher physical fidelity than those offered by Reynolds-averaged Navier-Stokes simulations while avoiding the intractable computational expense of direct numerical simulations. While implicit large-eddy simulations have seen widespread use for high-speed turbulent flows, it is unclear how the underlying stability techniques of the computational algorithms interact with added explicit turbulence models. Specific questions include whether the former can substitute for the latter (implicit large-eddy simulation), whether the latter can by itself regularize an infinite-Reynolds number calculation, and the effect of simultaneously using both. In the context of a fourth-order finite-volume method, this study investigates the inter-
