A Priori Assessment of Prediction Confidence for Data-Driven Turbulence Modeling
Flow Turbulence and Combustion, 2017Although Reynolds-Averaged Navier–Stokes (RANS) equations are still the dominant tool for engineering design and analysis applications involving turbulent flows, standard RANS models are known to be unreliable in many flows of engineering relevance ...

Recent developments and research needs in turbulence modeling of hypersonic flows
The Physics of FluidsHypersonic flow conditions pose exceptional challenges for Reynolds-averaged Navier–Stokes (RANS) turbulence modeling. Critical phenomena include compressibility effects, shock/turbulent boundary layer interactions, turbulence–chemistry interaction in ...

Machine learning methods for turbulence modeling in subsonic flows around airfoils
The Physics of Fluids, 2018Reynolds-Averaged Navier-Stokes(RANS) method will still play a vital role in the following several decade in aerospace engineering. Although RANS models are widely used, empiricism and large discrepancies between models reduce the reliability of ...

Attached Eddy Model of Wall Turbulence
Annual Review of Fluid Mechanics, 2019Modeling wall turbulence remains a major challenge, as a sufficient physical understanding of these flows is still lacking. In an effort to move toward a physics-based model, A.A.

Journal of Applied Mechanics, 1983
The historical development of and motivation for turbulence modeling is briefly surveyed. The models of various levels are described, and the performance of second-order models discussed. The various basic constraints to which second-order models are or are not subject are considered, including invariance, material frame indifference, realizability ...

Turbulence-Model Predictions for Turbulent Boundary Layers
AIAA Journal, 1974A set of turbulence model equations, originally postulated by Saffman, forms the basis of this three-part study of steady turbulent-boundary-layer structure above a flat plate. In one part of the study the turbulence equations are integrated through the viscous sublayer by means of time-marching numerical integration techniques and the constant in the ...

The Aeronautical Journal, 1982
An informal Working Party was set up in October 1980 to review the present state-of-the-art in turbulence modelling for aeronautical applications and to make recommendations for future progress in this field. The report assesses the extent to which further developments in design and prediction methods for both external and internal flow are dependent ...

Behaviour of turbulence models near a turbulent/non-turbulent interface revisited
International Journal of Heat and Fluid Flow, 2005Abstract The behaviour of turbulence models near a turbulent/non-turbulent interface is investigated. The analysis holds as well for two-equation as for Reynolds stress turbulence models using Daly and Harlow diffusion model. The behaviour near the interface is shown not to be a power law, as usually considered, but a more complex parametric ...
