Hello,
I want to simulate turbulent airflow inside a chamber using Fluent 6.3. I want to do it by choosing LES as the viscous model. When I choose LES the there is no explicit option for near wall treatment. Would you please let me know how can I define my near wall treatment approach when LES is selected as the viscous model? Thanks Khosrow |

Fluent automatically switch on the classical wall law wherever a high y+ is detected.
This is actually a blended linear-log profile dependent on the y+ value. Another option available in fluent is to switch on the werner and wengle model via TUI. It follows a different approach based on a power law velocity profile. |
