Reynolds Stress

Jade M · March 31, 2010, 15:06

What do BSL and SSG stand for in BSL Reynolds Stress and SSG Reynolds Stress? Does BSL stand for baseline? This terminology seems to have appeared in Menter's 1994 AIAA Journal paper. BSL and SSG appear to be standard terminology -- not specific to CFX, correct?

What is the best source which defines these things for someone who is new to turbulence?

Thank you very much for any information.

The best way of seeing what is behind the models is firstly by reading the documentation then chasing its references. There are also some unreferenced journal articles about which describe the development of these models, your CFX support person should be able to provide you with these.

I do not see this in the literature. Can anyone answer my question? Thanks so much.

I think Wilcox's book "turbulence modelling for CFD" will cover these models.

For those who are interested, below are several acronyms

BSL = Baseline
SST = Shear Stress Transport
SSG = Speziale, Sarkar, Gatski
RSM = Reynolds Stress Model
EARSM = Explicit Algebraic Reynolds Stress Model
LRR = Launder, Reece and Rodi
IP = Isotropization of Production
QI = Quasi-Isotropic
LES = Large Eddy Simulation
DES = Detached Eddy Simulation
SAS = Scale Adaptive Simulation
RANS = Reynolds Averaged Navier-Stokes
RNG = Renormalization Group
SGS = subgrid scale
WALE = Wall-Adapted Local Eddy-Viscosity
