The near wake of a sinusoidal wavy cylinder is investigated using time-resolved particle image velocimetry (TR-PIV). The wavy cylinder has a large spanwise wavelength of six mean diameters. TR-PIV measurements are taken in three orthogonal planes in the near wake at a Reynolds number Re = 3.0 × 10 3...
