Hi every body,

how can I determine mixing length and turbulence intensity in a k-epsilon high Reynolds ?

Sometimes these values can be found in literature. A good rule of thumb is that the turbulence length scale is an order of magnitude smaller than the hydraulic diameter for duct flow, and the turbulence intensity is of the order of 0.001. See page 6-12 0f the STAR-CD Methodology document.
