have you tried the module viscosity and turbulence?

The most commonly used is the Reynolds number dependent drag, IDRG=4, which requires a linear and quadratic flow loss coefficients. The Manual gas more details on choosing those.

So, would you help me. I wish someone can check my simulation and give some reports if there is something wrong. Thank you for your help. Please send your e-mail, than i will send you my works to to your email. my e-mail: oky.andytya.net@gmail.com Regrads, OKY Andytya P note: I use ANSYS Fluent 6.3 [CFD]
