| 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. |
