Wind blowing at a steady velocity V toward a vertical column of diameter, D, generates velocity fluctuations behind the column that have a frequency ω. The frequency of the generated velocity fluctuations can also depend on the density and viscosity of the air. Determine a nondimensional functional relationship that relates the frequency of the velocity fluctuations to the influencing variables. Identify any named conventional dimensionless groups.
