Hi,

Could anyone tell me where I can find, preferably online, information regarding the use of relaxation parameters and how the variation of these can affect the convergence. I am modelling a fully unsteady, Sliding mesh cavitation model of a single blade centrifugal pump. I also model without unsteadiness. I do not solve the Energy equation. Any help, even books, papers etc would be appreciated. The model is in Fluent.

Thank you.

Start with chapter 17 in Fletcher, "Comp. Techniques for Fluid Dynamics" (Vol. II) and check the given references.
