klausb Senior Member Klaus Join Date: Mar 2009 Posts: 306 Rep Power: 23	Hello, I want to investigate a hydrofoil operating in a Re-range between 350.000 and 1.500.000 using simpleFoam. The chord length is about 100mm. In order to setup the simulation, I need to define the turbulent intensity and turbulent length scale. According to my desk research, the turbulent intensity is in the range of 1%-5% - Any hints on what value to choose? What would be an appropriate turbulent length scale for the case? Klaus
