Large-eddy simulation (LES) has proven to be a computationally tractable approach to
simulate unsteady turbulent flows. However, prohibitive resolution requirements induced by …

Great efforts have been dedicated during the last decades to the research and development
of hypersonic aircrafts that can fly at several times the speed of sound. These aerospace …

A review of fundamental research in combustion stabilization for hypersonic airbreathing
propulsion is presented. Combustion in high-speed airbreathing propulsion systems …

While data-based approaches were found to be useful for subgrid scale (SGS) modeling in
Reynolds-averaged Navier-Stokes (RANS) simulations, there have not been many attempts …

The paper provides a brief introduction to the near-wall problem of LES and how it can be
solved through modeling of the near-wall turbulence. The distinctions and key differences …

A finite-volume method is developed for simulating the mixing of turbulent flows at
transcritical conditions. Spurious pressure oscillations associated with fully conservative …

The interaction between an incident shock wave and a Mach-6 undisturbed hypersonic
laminar boundary layer over a cold wall is addressed using direct numerical simulations …

A review of recent research outcomes in downstream flow choking-driven unstart is
presented. Unstart is a flow phenomenon at the inlet that severely reduces the air mass flow …

We present a computational analysis of the reactive flow in a hypersonic scramjet engine
with focus on effects of uncertainties in the operating conditions. We employ a novel …

The combustion instability in a laboratory-scale direct-connect hydrogen-fueled scramjet
combustor is investigated numerically. The numerical simulation has been carried out using …
