Characterisation of vortex shedding on a hydrofoil using PIV measurements

An experimental study of vortex shedding on a hydrofoil Eppler 817 was conducted using two-dimensional two components Particle Image Velocimetry. This foil section’s characteristics are adapted for naval applications but sparsely documented. The characterization the flow modes realized based statistical data such as mean velocity field and standard deviation vertical velocities. were acquired at very low Reynolds number which not often covered four angles attack ranging from 2◦ to 30◦. A map different characteristic made this space parameters used identify configurations exhibiting particular dynamics.
