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 ex...

In this study, we evaluate the usefulness of mature landfill leachate (MLL) as a carrier allowing hydrodynamic cavitation (HD) brewery spent grain (BSG). The HD experiments were conducted using an orifice plate with conical concentric hole 3/10 mm (inlet/outlet diameter) constriction in device. initial pressure was 7 bar and number recirculation passes through zone reached 30. results showed th...

Mechanical surface modification such as shot peening offer powerful enhancement of fatigue properties metals and other materials. Cavitation usually causes damage in hydraulic machineries. However, careful selection process parameters allowed developing an approach known “cavitation peening.” Its advantage is roughness increase lower than conventional there are no solid collisions involved. As ...

The blockage effect is one of the drawbacks in use cavitation tunnels, which may considerably interfere measurements hydrodynamics model-scale propellers. literature presents some methods to correct acquired values, such as Glauert method, but deduction this method does not consider effects. This paper aims CFD tools compare and analyze different levels blockages on thrust, torque, hydrodynamic...
