Particles in air flow

BachelorM7 · October 9, 2015, 05:59

Hello.

We are working on a bachelor about optimization of an ejector.
A quick overview of the structure:
There are two inlets and an outlet. In one of the inlets water flows, which is delivered by a pump. In the second inlet particles/powder will be sucked up from a bag. The water and the powder is mixed and leaving the ejector through the outlet.
The issues are: how do I add both powder and air at the other inlet?
I use CFX.

Best regards

First thing, you would need to post the query in CFX forum. Apart from that a rough sketch or model would evoke much better support. You would have to use a mixing model simulation. There are reasonable amount of tutorials online relevant to your work.

I'm new in here, so I don't know have to post a picture.

Yes, but I don't know which mixing model?
