Propulsion (<strong>in</strong>clud<strong>in</strong>g Cavitation)<br />
Cavitat<strong>in</strong>g Flow Over a Hydrofoil<br />
Cavitat<strong>in</strong>g flow over a cambered two-dimensional w<strong>in</strong>g<br />
section was simulated us<strong>in</strong>g <strong>ANSYS</strong> Fluent CFD solver. The<br />
flow angle over the NACA 66 (MOD) hydrofoil is chosen to<br />
represent conditions that are common <strong>in</strong> water pump <strong>and</strong><br />
mar<strong>in</strong>e propeller applications. Excellent agreement with<br />
experimental data is obta<strong>in</strong>ed for mid-chord cavitation, <strong>and</strong><br />
satisfactory agreement is obta<strong>in</strong>ed at the trail<strong>in</strong>g edge of the<br />
cavitation region.<br />
Pressure coefficient as a function of normalized chord length<br />
show<strong>in</strong>g <strong>ANSYS</strong> Fluent results compared with experimental data<br />
Contours of vapour volume fraction show cavitation <strong>in</strong> the mid-chord region<br />
