Expansion - Deflection Nozzle
Posted May 25, 2010, 5:58 AM EDT 3 Replies
I'm a student in the Von Karman Institute in Belgium.
I've a project about an expansion - deflection nozzle. I would like to realize a Comsol model of it. You can see on the pic that it's pretty simple. Just a nozlle with a chamber pressure at the top (102 bar and 2400 K) and a atmosperic pressure for the outlet. I've choose a k-eps model but my calculations never converge !! I don't know what to do. If you can help me.
Just to know, it's not my first model with Comsol. But I cannot understand what happend with this one.
If you need more details, tell me.
Thanks a lot for your answers !
