Flow Over a Hydrofoil Using K - Epsilon
 
I am attempting to replicate a very standard study of air flow over an airfoil but for water. So I took the profile of a NACA 0012 foil (scaled down to 0.15 and 0.3 meters). I am trying to run the model in water at velocity of 1-3 m/s for angle of attack between 0-40 degrees. I am getting some results off and on that are highly unusual and a few cases will not converge at 0.001. I am concerned about my initialization of k and epsilon. I am unclear on how I should handle them given that the case is water.
