Differential Reynolds-Stress Modeling for Aeronautics
AIAA Journal, 2015A comparison of two differential Reynolds-stress models for aeronautical flows is presented. The ω model herein combines the Speziale–Sarkar–Gatski pressure–strain model with the Launder–Reece–Rodi model toward the wall, where the length scale is supplied by Menter’s baseline ω equation.

Model functions of Reynolds stress models
The Physics of Fluids, 1988A Reynolds stress (Re-stress) model for the prediction of shear flows is presented. Special attention is paid to the determination of the model functions. First, the general modeling assumptions are discussed and the modeling of the equations is then described in detail. It is shown that by successive analysis of different types of flows a set of model

Reynolds Stress Models for Shock-Turbulence Interaction
2019A systematic deficiency of current turbulence models which are based on the Reynolds-averaged Navier-Stokes equations (RANS) is their inability to correctly predict the interaction of turbulence with shocks. This is because RANS models do not account for the unsteady motion or fragmentation of the shock wave within the interaction zone.

Simulation of a Variety of Wings Using a Reynolds Stress Model
Journal of Aircraft, 2014The Wilcox 2006 stress-ω model, a Reynolds stress model, implemented in both the NASA Langley codes FUN3D and CFL3D, has been used to study a number of 2-D and 3-D cases. This study continues the assessments of the stress-ω model by simulating the flow over two wings: the DPW-W1 and the DLR-F11 wings.

Reynolds-stress-transport modeling for compressible aerodynamics applications
AIAA Journal, 1999Progress is reported in the development of a nonlinear Reynolds-stress-transport model for compressible, turbulent flow. The focus is on a variation of a particular cublc model that does not require the usual topography-related parameters, such as normal-to-wall vectors.

Modelling of rapid pressure—strain in Reynolds-stress closures
Journal of Fluid Mechanics, 1994The most general form for the rapid pressure—strain rate, within the context of classical Reynolds-stress transport (RST) closures for homogeneous flows, is derived, and truncated forms are obtained with the aid of rapid distortion theory. By a classical RST-closure we here denote a model with transport equations for the Reynolds stress tensor and the ...

Reynolds stress model involving the mean spin tensor
Physical Review E, 2004In this work, we develop a Reynolds stress model along the line of the approach presented by Commun. Nonlinear Sci. Numer. Simul. 9, 543 (2004)]], aiming to assess the role and contribution of the mean spin tensor in turbulence modeling. Here, the constitutive functional for the Reynolds stress depends on the mean spin tensor as well as the mean ...

Momentum Transfer Model for Reynolds Stresses
Journal of the Hydraulics Division, 1977As with most other natural phenomena turbulence has to be approximate by a simplified mathematical model to be approximated by a simplified mathematical model to render its effects amenable to engineering analysis and for turbulence there are few models that can match in simplicity and effectiveness the phenomenological momentum transfer model ...

On the mathematical modeling of the Reynolds stress's equations
28th Aerospace Sciences Meeting, 1990By considering the Reynolds stress equations as a possible descriptor of complex turbulent fields, pressure-velocity interaction and turbulence dissipation are studied as two of the main physical contributions to Reynolds stress balancing in turbulent flow fields.

An explicit algebraic Reynolds stress model in turbulence
International Journal for Numerical Methods in Fluids, 2006A new algebraic Reynold stress model is constructed with recourse to the realizability constraints. Model coefficients are made a function of strain and vorticity invariants through calibration by reference to homogeneous shear flow data. The anisotropic production in near-wall regions is accounted for substantially by modifying the model constants Ce ...
