hi every body !!!!!!!
i wanna know that how i can calculate turbulent intensity for my case , in fluent !! i find this relation for fully developed flow in tube I=0.16*(Re(dh))^(-1/8) !!! but my geometry isnt tube !!!! its 3D, in inlet has rectangular cross section, & in outlet a cylinderical Cross section !!!! its alittle complex!!!!! Plz help me !!!!!!!!!!!!! SaHa |

Dh is the hydraulic diameter.
Dh = 4.A / P with A = Area and P=perimeter
