Third year project - CFD nozzle design

[stokie1991]

Hi, for my third year project i have got to design a nozzle to fit a fire extinguisher. However firstly i must analyse fluid flow within said nozzle, but i have no idea how to use GAMBIT/FLUENT and finding it difficult to find relevant user guides on the internet. Anyone care to offer some advice? Thanks

Are you using Pointwise to draw the mesh? That project is pretty straightforward. I've done a lot of CFD, but haven't used either of those programs. Although, most of them are pretty similar.

Clearly he isn't using Pointwise because he is asking for GAMBIT help. If Pointwise is available though, it should be used. It is so much nicer.

Like I said, never used them before... Only heard of Fluent. I use CFD++ and a new one made by NASA that no one has yet. At uni I used ACE/FASTRAN, which is a terrible program.

Yeah I have been instructed by the university to use Gambit to create the mesh file, then import that into FLUENT to study the fluid flow within a nozzle.

Also I was wondering is it possible to model the nozzle in ProEngineer and then export it into Gambit/Fluent, as ProE is a lot more user friendly than gambit

Yes you can import geometry like that but I'm not an expert on the topic. I am not a CFD guy and am going by what I know from the CFD guys I work with.

Are you doing a 2d or 3d model? Are you using a super computer or just a uni one?
