Error in Implementation of Pressure-Strain Correlation in SSG Model?!

Hello everybody,
studying the SSG Reynolds-stress model on openfoam.com (http://www.openfoam.com/documentatio...8C_source.html) I came across something that confused me. First, the related documentation (http://www.openfoam.com/documentatio...e-ras-ssg.html) is very sparse and maybe also erroneous as it seems to be under construction. The model equations in the documentation seem to contain a redundant in the second right hand side term (i.e. the first term of the pressure-strain correlation). Also, the documentation, as well as the source code show a sum within the same expression as above Code:
fvm::Sp(((C1_/2)*epsilon_ + (C1s_/2)*G)*alpha*rho/k_, R) Code:
G Code:
epsilon_ I'm new to the OpenFOAM source code, so please take it easy on me ... ... but is it possible that there's an error in the implementation of the SSG model? Thanks in advance for any help or comments Last edited by NablaDyn; October 23, 2017 at 09:38. |
