Abstract

Abstract

The steady partially cavitating flow around two-dimensional hydrofoils was simulated numerically by the low-order potential-based boundary integration method.The caviy shape and length are determined for given cavitating numbers in the course of iteration by satisfying the kinematic and dynamic boundary conditions.The re-entrant jet model and the pressure-recovery close model are adopted to replace the high turbulent and two-phase wake forming behind the cavity.The results are compared with the other published numerical ones.
- two-dimensional hydrofoil,
- partial cavitation,
- cavity termination model,
