【 摘 要 】

The results of testing the SIV method (Smoke Image Velocimetry) for two-dimensional instantaneous flow velocity vector fields measurements were presented for the case of flow in the near wake of a cross circular cylinder at Reynolds number of 3900. Measured profiles of the streamwise and transverse flow velocity components in the near wake of the cylinder at different distances were compared with the direct numerical simulation and experiments of other authors. The capabilities of SIV method were confirmed.
