If the viscous model is laminar, what equation does fluent solve?


Thank you!

The Navier-Stokes equations discretized by the finite volume method...

Thank you flotus1!

But I don't know can I trust the result ?

What is the difference between laminar model and turbulence model? Do you have some document about it ? If you have some, can you tell me ?

There is no turbulence model involved when the viscous "model" is set to laminar.

Thank you .
I got clear about it . Does it like a DNS simulation? But because of the mesh size , it can't get the turbulence.

With the viscous model set to laminar in Fluent, you are performing a DNS.
But as you already noticed, the results are affected by the discretization so you have to be very careful when trying to simulate turbulent flows.

I wonder if anyone has ever successfully conducted a DNS of a 3-dimensional turbulent flow with Fluent.
