  Hi, I am using k-Epsilon turbulant model in which i am not able to find what value of k and epsilon i have to put. I am doing fluid flow and heat transfer analysis in wavy channel. At the inlet boundary condition many option is given as an input like values of k-Epsilon, Turbulent intensity and hydraulic diameter etc. Which option and values will be good for better solution of the physics?

  you can use tur intensity and hyd dia if you know your perimeter. if you dont have much info then you can go ahead with default turb intensity and visc ration.
