Richardson number for swirling flow

March 15, 2002, 06:53

Dear colleagues.

Could you inform me any articles about using Richardson number for modeling of swirling, rotating and recirculating flows?

Thank you.

Victor.

Ri = [(1/density)*(d(density)/dr)*(u(centripetal)**2/r)]/[(du(z)/dr)**2]

A. Hellsten has proposed a definition that can be applied to any geometry. You can see the paper

Any expressions available for the prssure drop in a recirculating flow is requested to be communicated.Thanks.
