A novel laminar kinetic energy model for the prediction of pretransitional velocity fluctuations and boundary layer transition

A new non-linear RANS model with enhanced near-wall treatment of turbulence anisotropy

“…It has been gaining popularity in academia and industry, and its validity for scientifc research has been established [62,63]. The implementation of the model follows the methodology suggested in [64]. A steady state incompressible fow solver simpleFoam (consistent), based on the SIMPLEC algorithm, available in OpenFOAM is used to perform the calculations.…”

Development of an Analytical Wall Function for Bypass Transition

“…For one-equation transition models, a variety of γ transition models were proposed: Lodefier et al [32], Wang and Fu [33], Durbin [34], Ge et al [35], Menter et al [36] and Juntasaro et al [37]. Besides the intermittency factor γ, Mayle and Schulz [38], Walters and Leylek [39], Walters and Cokljat [40] and Medina et al [41] developed the k L transition model. As an alternative to the kinetic energy of laminar fluctuations k L , Lopez and Walters [42] proposed the ν 2 transition model, where ν 2 is the wall-normal velocity fluctuation made approximately equal to the difference between the turbulent kinetic energy k and the kinetic energy of laminar fluctuations k L , i.e., ν 2 ≈ k − k L .…”

A Short Review on RANS Turbulence Models

“…In the last three decades, many numerical methodologies have been used commonly to numerically analyses turbulent flow such as Reynolds-Averaged Navier-Stokes (RANS) model [5][6][7][8][9][10], Large Eddy Simulation (LES) model [11][12][13][14] and Direct-Numerical Simulation (DNS) [15][16][17] and also other flow problems [18][19][20][21]. DNS pursues a thorough three-dimensional resolution all the turbulent scales in time and space by solving the Navier-Stokes equations and this is the most accurate approach for simulating turbulent flow [14,[16][17].…”

“…All turbulent length scales are modeled in RANS. It has been the backbone for the last few decades in modern CFD method for simulating the turbulent flow due to its less costing computing requirement and affordable to use [5][6][7][8][9][22][23][24].…”
