Simulation study on active cavitation suppression for a typical hydrofoil

Abstract An active cavitation suppression structure with jet holes on its surface is proposed for a typical hydrofoil (NACA66 MOD). Based the homogeneous equilibrium model and Zwart-Gerber-Belamri model, characteristics around before after are provided at operating condition investigated through simulation. Simulation results show that capable of regulating controlling flow field, to certain extent, suction inhibit development shedding cavitation. Four groups different rates set up, it found increase rate, effect gradually increases, lift-to-drag ratio decreases. The research shows can achieve 69.35% under premise ensuring range hydrodynamic performance does not exceed 5%. By coupling distribution shape, re-entrant pressure field fluid flowing studying periodic change mechanism suppress analyzed.
