Baldwin-Lomax
Hi! I want to use Baldwin-Lomax model, but don't know how in CFX. As I known that, in B-L model, eddy viscosity is given by mixing length and vorticity. But in CFX the zero equation model is control by eddy viscosity value, velocity scale and eddy length scale. How to deal with that? Thanks.

Re: Baldwin-Lomax
Why not setup an AV equation to solve the the eddy viscosity and then use that the set the value of the eddy viscosity?

Re: Baldwin-Lomax
Thanks for replying! But what does the AV equation refers to? However, in B-L Model the eddy viscosity varies along the y axis. How it can be instead by a certain value?

Re: Baldwin-Lomax
An AV equation is an "additional variable' equation. It can include transient, diffusion, advection, and custom user sources.
I'm not sure of the exact B-L details, but perhaps you could do it this way. |
