Physical Modeling of Flow around the Underwater Tidal Power

The flow near the underwater tidal power with orthogonal vertical hydro turbines is studied. The flow is modeled using the particle image velocimetry (PIV). The series of experiments study the flow near the model. In the experiments flow is approximated by the two-dimensional problem; this approximation is related to the shape of the power, a characteristic linear dimension greater length relative to other sizes. According to the results of post processing experiments instantaneous velocity vector fields were obtained, then they were transformed into the time-averaged velocity field and streamlines
