February 12, 2004, 17:12	Simple question for friction velocity	#1
jay Guest Posts: n/a	Hi.. I have a simple question.. How to calculate the wall friction velocity (Utau) in three dimensional case? In 2-d, Utau = sqrt((Mu(du/dy))/rho).. but.. in case of 3-d, i think Utau = sqrt((Mu(du/dy+ add something))/rho) or.. how can I express the Utau or thw wall shear stress in 3-D? please answer for me.. when it is in x-y-z coordinate, x is streamwise, y is the normal direction, z is the spanwise.. Thank you..
