hi, i have a very basic question. what happens when one tries to model a highly turbulent flow with pure Navier-Stokes equations - i.e. without any turbulence modeling?

normally Navier Stokes equations should hold even for turbulent cases, but the intense fluctuations that are inherent in turbulent flows make its use impossible. i want to know however what the practical consequences of using such a basic approach with turbulent flows are.

cheers

It's called DNS. Look it up on any CFD textbook.
