January 5, 2014, 16:06	turbulence specification methods	#1
Tariq Feroze New Member Tariq Join Date: Oct 2013 Posts: 6 Rep Power: 13	how to decide what turbulence specification method should be chosen for pressure outlet boundary condition ( k and epsilon, intensity and backflow hydraulic diameter, intensity and viscosity etc) what is back flow hydraulic diameter, how to calculate it, is it the same as hydraulic diameter? similarly how to decide about the turbulence specification method for velocity inlet? is it a must to check the y+ value of the mesh for all kind of turbulent simulations?
