Image processing of the near wakes of stationary and rotating cylinders

  • J. Massons (a1), X. Ruiz (a1) and F. Díaz (a1)


Statistical properties of the position of the turbulent/non-turbulent interface in the near wake of stationary and spinning cylinders have been measured for Re = 2000, using image processing techniques. The results include the first statistical moments, intermittency and burst-rate profiles, auto- and cross-correlation functions, auto- and cross-spectra and phase spectra. They indicate that the rotation of the cylinder causes substantial changes in the structure of the flow.
