Thank you very much! It really helped a lot
That pdf document is really good, it confirmed what i was thinking.
I realized with my calculations that if I define all properties constant, the pressure drop is not changing. Then I set the water properties as IAPWS EOS (International...
If you don't have the tutorials, search the web. There is a lot of information to all those questions that may arise at the beggining. If you still struggle, then I recommend you cfd-online.com forum
For your simulations, you would like this tutorial
I don't know if i understood properly what you are doing, but you don't need to model any "wind tunnel", just the model of what you want to test. then you give the meassures of your wind tunnel, for example: 3m distance in +x direction, 10m in -x, 0.05m in -z, etc
Then you will get a squared...
Try with ANSYS Workbench and then CFX or Fluent as solvers...is really easy to do the mesh with workbench. Just import your geometry and create an enveloping body (dont know how that function is called in the english version).
Hope it helps!
Cheers
Hello everybody
The problem is about a very simple heat exchanger.
One pipe with cold water at the inlet and at some points heat is applied uniformly. Assumed no buoyancy. Wall is smooth and with no slip.
I simulate different a matrix of volume flow rates and inlet water temps. For 5...
