Hi Foamers!

I am simulating a multiphase problem using Laminar solver. I am planning to run the problem at a Reynolds number at the order of magnitude of 10^5. The reason is because I would like to treat the simulation as DNS (kind of solving Navier Stokes directly), and I would like to avoid any complexities such as using spectral method in my simulation. However, will the simulation be realistic, as the name suggest, Laminar model seems like suitable for the case of problem involving flow with low Re. Some mentioned that forced convergence is applied at high Re, therefore affecting (sacrificing) the accuracy of the solution. Appreciate any advice on the suitability of Laminar turbulence model for relatively high Re.

Many thanks
