Automatic Wall Treatment

October 2, 2008, 06:01

Hi,

I have a question concerning the automatic wall function. I read that this model blend omega and u_tau at the wall and set k to zero. I wonder, how one treats the kinetic energy production at the wall!? And I am not sure, how one would do the implementation approach for the u_tau condition. I think one would adjust the viscosity at the wall, but I am not sure, how to set!?

The scalable wall function is just usefull for high-Re models, when using small y+ values, isn't?

Would be nice, if you have any suggestion or articles for my questions! Thanks! Fab

Hi, me again...

was the question too stupid or does no one have any idea!?
