"I would still like to use data from viscous turbulent flow simulation and compare it to analitical results"

Additionally, the analytical equation for the venturi meter, derived from Bernoulli's theorem, assumes irrotational flow (no rotational or swirling motions) and laminar flow. The complex flow behaviors are well captured by the Navier-Stokes equations, which are solved using CFD.
