Abstract

The frequency of eddy shedding by a circular cylinder at constant Strouhal number is shown to be suitable for the measurement of flow velocity. A wind speed monitor and regulator designed on this principle for an on-line experiment has operated successfully in the speed range 4-20 m s-1, and the system is adaptable to other speed ranges.
