Hi!
does a reasonable guideline for setting k, eps, nut, nutilda boundary-conditions related to the given problem? (e.g. zeroGradient, fixedValue, if fixed, what quantitative value, etc.). What types of BC can be used, anyway for pipe-flow, free-stream convection, etc? I would be nice to have a guideline to have a reasonable start before exploring the solution sensitivity to the given BC. Regards, Kriz |

Hi!
For external flows there is an informative paper by Spalart: Philippe R. Spalart, Christopher L. Rumsey: Effective Inflow Conditions for Turbulence Models in Aerodynamic Calculations, AIAA Journal vol. 45, no. 10, 2007 Regards, Luise |
