Abstract

A new device for air lubrication called Winged Air Induction Pipe (WAIP) is studied in the present work. The device, which consists of angled hydrofoil uses the low-pressure region produced above the hydrofoil as ship moves forward. The low pressure drives the atmospheric air into the water in certain velocities which the pressure is negative compare to atmospheric pressure. A computational fluid dynamics approach is presented to study the effect of hydrofoil clearance of Winged Air Induction Pipe in drag reduction experienced by the plate which WAIP attached. The well-known 'volume of fluid' model and k-ω SST (shear stress transport) turbulence closure model have been used in the 2D numerical simulation in ANSYS Fluent. The numerical simulation is carried out with different configuration of hydrofoil clearance and angle of attack. Effects of these parameters on total drag force and drag reduction are reported. The reduction of drag force is found to increase to about 10% compared to bare plate configuration.
