Laminar case: start with the most simple arrangement, even when the flow is turbulent.Sidemountyucatan wrote: ↑Fri Jan 15, 2021 4:30 pm- Thx, looks fine. It is meant to be volume flow each face. Must it be corrected ?
- You processed it as a laminar case but isn't the flow through the nozzles turbulent ? Does the laminar model describe the flow near the nozzles correctly ?
- So, I thought maybe it is necessary to define each nozzle as a separate inlet in the model. But your answer tells me it's not, right ?
Could it be done ?
Starting with the most simple arrangement means that you start with the most simple arrangement .Sidemountyucatan wrote: ↑Mon Jan 18, 2021 7:34 amOne last question to the "Laminar"-calculation mode:
You wrote "Laminar case: start with the most simple arrangement, even when the flow is turbulent." What does it mean specifically ?
I mean, which calculation scheme hides behind this mode ? Are RANS-equation being solved ? How is turbulent viscosity handled ?
I try to understand what the software is doing.
Thx for answer.
You can see the used solvers/gradient schemes in the fvSchemes/fvSolution files in the system folder after case writing.Sidemountyucatan wrote: ↑Tue Jan 19, 2021 12:37 pmI appreciate the discussion a lot. But maybe we missunderstood each other. What I was asking for is the set of formulas being solved in the "laminar case".
I suppose Navier Stokes equations are solved aswell, right ? Is it kind of DNS ?
But now another point: which further approach would you suggest. Currently the "laminar case" is running and it looks fine. Afterwards I will try a run with k-w-SST. But I guess the error message will show up again. What approach would you use ?
