Influences of the turbulence model and the slot width on the transverse slot injection flow field in supersonic flows
TL;DR: In this article, the effect of the turbulence model and slot width on the transverse slot injection flow field has been investigated numerically based on the grid independency analysis, and the predicted results have been compared with the experimental data available in the open literature.
Journal ArticleDOI
Transverse jet in supersonic crossflows
TL;DR: In this article, the transverse jet in supersonic crossflows has been summarized systematically from four aspects, namely single injection, multiport injection, interaction between jet and vortex generator, and interaction between the jet and shock wave.
Journal ArticleDOI
Hydrogen/air supersonic combustion for future hypersonic vehicles
TL;DR: In this paper, a 3D Large Eddy Simulations (LES) was used to analyze the supersonic hydrogen combustion in the Hyshot II scramjet engine, which showed very complex structures due to the interaction between the four sonic H 2 crossflow injections and the airstream flowing at M ǫ = 2.79.

Wei Huang,Li Yan +1 more
TL;DR: In this article, the transverse injection flow field has an important impact on the flowpath design of scramjet engines and the mixing process between the fuel and the supersonic freestream.

Ignition, flame structure and near-wall burning in transverse hydrogen jets in supersonic crossflow
Mirko Gamba,M. Godfrey Mungal +1 more
TL;DR: In this article, the authors investigated the properties of transverse sonic hydrogen jets in high-temperature supersonic crossflow at jet-to-crossflow momentum flux ratios between 0.3 and 5.0.

Journal ArticleDOI
A new version of detached-eddy simulation, resistant to ambiguous grid densities
Philippe R. Spalart,Sébastien Deck,Michael Shur,Kyle D. Squires,M. Kh. Strelets,Andrey Travin +5 more
TL;DR: In this paper, the authors proposed the DES97 model, denoted DES97 from here on, which can exhibit an incorrect behavior in thin boundary layers and shallow separation regions, when the grid spacing parallel to the wall becomes less than the boundary-layer thickness.
Journal ArticleDOI
A hybrid RANS-LES approach with delayed-DES and wall-modelled LES capabilities
TL;DR: In this article, a CFD strategy is proposed that combines delayed detached-eddy simulation (DDES) with an improved RANS-LES hybrid model aimed at wall modelling in LES (WMLES).
Journal ArticleDOI
Generation of Turbulent Inflow Data for Spatially-Developing Boundary Layer Simulations
TL;DR: In this article, a method for generating three-dimensional, time-dependent turbulent inflow data for simulations of complex spatially developing boundary layers is described, which is essentially a variant of the Spalart method, optimized so that an existing inflow?outflow code can be converted to an inflow-generation device through the addition of one simple subroutine.

Wall-layer models for large-eddy simulations
Ugo Piomelli,Elias Balaras +1 more
TL;DR: In this article, the authors present three broad classes of approaches: bypassing this region altogether using wall functions, solving a separate set of equations in the nearwall region, weakly coupled to the outer flow, or simulating the near-wall region in a global, Reynolds-averaged, sense.
