Model of Swirl Tube (Axial Reverse cyclone)
 
Hello, everybody. I have noticed that there are so many people interested in cyclone seprators. And now i am doing the Model of Swirl Tube (Axial Reverse cyclone),(see A.C.Hoffmann's Book or paper). I have two questions about it when using Fluent?

1. How to get the accurate 3D guide vane model with Gambit?

2. The swirl tube is simple,but also comlicated flow behavior. So RSM is a better choise ? DPM ?

Thanks in advance

2. RSM is greatly suggested for swirling flows, even if its convergence is always so complicated..... If you want to simulate particle separation, I think DPM is mandatory... fluid

Thanks But the guide vane is so important, beacause if it cannot be made with Gambit. The velocity profile calculated by Fluent must not be accurate.

The "cross talk" between the parallel swirl tubes as the third stage separator in FCC can be simulated with FLuent?

Thanks your reply

sorry, it in not my application field and I can't be "more" useful than I have already done... :-P fluid

Theres a Gambit plug-in called G-Turbo that can be used to create geometry for blades which could be of use

Ah, ok. Thanks, fluid

Thanks

Now I am using Fluent 6.2.1. Where to find The Gambit plug-in called G-Turbo ? Could Neil sent one for me ?

Does G-Turbo have trial edition? Anybody can provide some useful infomaion.
