A Novel Algebraic Stress Model with Machine-Learning-Assisted Parameterization
Energies, 2020 Reynolds-stress closure modeling is critical to Reynolds-averaged Navier-Stokes (RANS) analysis, and it remains a challenging issue in reducing both structural and parametric inaccuracies. This study first proposes a novel algebraic stress model named as

Theoretical modeling of convection II. Reynolds Stress Model [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractThe Reynolds Stress Model (RSM) yields the dynamic equations for the second-order moments (e.g., heat fluxes) needed in the equations for the mean variables (e.g., mean temperature). The RSM equations are in general time dependent and non-local.

Revised Reynolds-Stress and Triple Product Models [PDF]
23rd AIAA Computational Fluid Dynamics Conference, 2017 Revised versions of Lag methodology Reynolds-stress and triple product models are applied to accepted test cases to assess the improvement, or lack thereof, in the prediction capability of the models. The Bachalo-Johnson bump flow is shown as an example for this abstract submission.

Analytical Model of the Time Developing Turbulent Boundary Layer
, 2007 We present an analytical model for the time-developing turbulent boundary layer (TD-TBL) over a flat plate. The model provides explicit formulae for the temporal behavior of the wall-shear stress and both the temporal and spatial distributions of the ...

RANS Equations with Explicit Data-Driven Reynolds Stress Closure Can Be Ill-Conditioned
, 2019 Reynolds-averaged Navier--Stokes (RANS) simulations with turbulence closure models continue to play important roles in industrial flow simulations. However, the commonly used linear eddy viscosity models are intrinsically unable to handle flows with non ...
