Answer Posted / n bala krishna
When a shedder bar is placed in a fluid, Karman vortices
are generated on the downstream side. The vortex frequency
is proportional to the flow velocity, and corresponds to a
specific range of Reynolds numbers.The vortex frequency (f)
is calculated by the formula; f=St*v/d
v: flow velocity, d: width of shedder bar, St: Strouhal
number
