Default modelling of RFR with two differnt rpm
Posts: n/a
Hi all, I am a CFX5.4.1 User. I have to model a rotating flow problem. It is like a conical annulus with inner surface at 1000 rpm and outer surface rotaing at 2300 rpm. How to model this with CFX 5. With rotating domain, I am given with 1. Free slip, 2. no slip and 3. counter rotainng wall. I do not find any of them of use to define a surface rotating at different rpm than thatr of the domain. Thanks for your time Veebs
