hi friends,

I'm working on hydrodynamic analysis of catamaran hull in turbulence flow with VOF method in low Reynolds number (Shallow water).

please give me your suggestions about the best turbulence modeling for this problem.

How is the reynolds number defined for this system? Based on depth of the water, not the length of the hull? Also, it's a fluid-fluid interface problem, so I'm guessing you're mainly looking at the water side fluid mechanics?

My method of determining a turbulence model might not be the best, but usually I test 2-3 models that I think would work, and if they all give me similar results, I just pick one and run with it.

Anyway, more details might help if you want someone to reply who really knows what they're talking about!
