SU2 v6.0 turbulence models.

raz · March 2, 2018, 05:06

Hi all,

Was curious if anyone could point me in the direction of the references behind the latest turbulence models added in SU2 v6.0. (SA_NEG, SA_E, SA_COMP and SA_E_COMP) I'm curious what are the exact differences as I'd like to do a turbulence modelling study on buffeting.

SIDE NOTE: Does anyone know how to make SU2 stop writing the *.csv solution every time step in unsteady simulations? I've had troubles using the WRT_CSV_SOL = NO command.

Regards,

searched the code and found out that:

SA_NEG = SA Negative

Allmaras, S. R., Johnson, F. T., and Spalart, P. R., "Modifications and Clarifications for the Implementation of the Spalart-Allmaras Turbulence Model," ICCFD7-1902, 7th International Conference on Computational Fluid Dynamics, Big Island, Hawaii, 9-13 July 2012.

SA_E = SA with Edwards Correction

Edwards, J. R. and Chandra, S. "Comparison of Eddy Viscosity-Transport Turbulence Models for Three-Dimensional, Shock-Separated Flowfields," AIAA Journal, Vol. 34, No. 4, 1996, pp. 756-763.

SA_COMP = SA with compressibility correction
