Phase-averaged measurements of the turbulence properties in the near wake of a circular cylinder at high Reynolds number by 2C-PIV and 3C-PIV

Phase-averaged measurements of the turbulence properties in the near wake of a circular cylinder... The near wake of a circular cylinder at high Reynolds number is investigated by means of 2D-PIV and stereoscopic PIV. Phase-averaged measurements of the instantaneous fields have been performed. The linear stochastic estimation (LSE) has been adapted to estimate the phase-averaged quantities. This avoids the long time acquisition and the large storage needed for phase averaging. A good comparison is achieved between the results of the conditional sampling and those of LSE. Therefore, the estimation has been applied to the three-component datas and allowed evaluation of the whole phase-averaged turbulent stress tensor. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals

Abstract

The near wake of a circular cylinder at high Reynolds number is investigated by means of 2D-PIV and stereoscopic PIV. Phase-averaged measurements of the instantaneous fields have been performed. The linear stochastic estimation (LSE) has been adapted to estimate the phase-averaged quantities. This avoids the long time acquisition and the large storage needed for phase averaging. A good comparison is achieved between the results of the conditional sampling and those of LSE. Therefore, the estimation has been applied to the three-component datas and allowed evaluation of the whole phase-averaged turbulent stress tensor.
