I have developed a model using Gambit 2.0 and have created a very fine mesh. The problem is cold flow (non-reacting) with 2 species entering via two separate inlets into an expansion. The problem ran well with the incompressible gas, however it does not work when I convert to ideal gas.
I have...
A couple of points...
The first is of course the density. The lower the temperature, the higher the density. That means you get more air into your inlet manifold per unit volume...
Thus, the more air yyou have, the more fuel you need. The more fuel you get, the more power you get.
That is the...
Yep, Fluent needs a separate modelling program.
Gambit is commonly used however there are other possibilities. You can generate your model in Pro Eng, Solid Edge, Ansys and others. Try the fluent website.
