Re-Entrant Jet Modelling of Partial Cavity Flow on Two-Dimensional Hydrofoils

摘要

A potential based panel is developed to predict the cavity flow on two-211u001edimensional hydrofiol sections. The Dirichlet type dynamic boundary condition on 211u001ethe cavity surface and the Newmann type kinetic boundary condition on the wetted 211u001esection surface are enforced. A re-entrant jet cavity termination model is 211u001eintroduced. A validation is accomplished by comparing the present calculations 211u001ewith caviation experiments of a modified Joukoswky foil and a NACA 66(MOD) a=0.8 211u001esection.
