Default Underrelaxtion SIMPLE-Algorithm

Hi everybody,

I have a question to SIMPLE-like algorithms. All these algorithms have to use strong underrelaxtion parameters for momentum or pressure-correction equations. At the beginning of outer iterations they have to be chosen much stronger than before converging. Is there any useful adaptive strategy for choosing the underrelaxation parameters. Does anybody have papers or other literature on this subject.

Thank you very much
