Friction velocity -- CFD-Wiki, the free CFD reference

Webobservations. Regardless of wind direction, friction velocity increases with increasing wind speed, and linear regression shows that the rate of increase is ~50% less than previously reported. However, a leveling-off or decrease in friction velocity with increasing wind speed is found under strong wind conditions using a bin-averaged method.
