TL;DR: In this paper, an approach which closely maintains the non-dissipative nature of classical fourth or higher-order spatial differencing away from shock waves and steep gradient regions while being capable of accurately capturing discontinuities, steep gradient, and fine scale turbulent structures in a stable and efficient manner is described.

TL;DR: In this paper, a 3D simulation of the incompressible Navier-Stokes equations is used to study flows where laminar boundary-layer separation is followed by turbulent reattachment forming a closed region known as a laminars separation bubble.

TL;DR: In this paper, a large-eddy simulation of the interaction between an impinging oblique shock and a Mach 2.3 turbulent boundary layer is presented, which does not introduce any energetic low frequencies into the domain, hence avoiding possible interference with the shock/boundary layer interaction system.

TL;DR: In this paper, the effect of compressibility on a plane mixing layer that is a prototype free shear layer, amenable to study by numerical simulation and experiment, is considered, and the full time-dependent compressible Navier-Stokes equations are solved numerically for a temporally evolving mixing layer employing a mixed spectral and high-order finite difference method.

TL;DR: In this paper, the authors present a direct numerical simulation of laminar separation bubbles on a NACA-0012 airfoil at Re-c = 5 x 10(4) and incidence 5 degrees.
