Abstract EN
The purpose of this paper is to study the two-phase flow around hydrofoil.
Experimental studies have been conducted in a channel with air-water flow for different angles of hydrofoil with different air and water discharges.
The paper describes experiments carried out in the channel with the rectangular test section of 100 x 30 x 800 mm.
The maximum inlet velocity at the test section for air is 1.115 m/s and for water is 0.022 m/s.
These experiments have been aimed to visualize the two phase flow phenomena as well as to studies effect of pressure difference through channel with hydrofoil.
All sets of flow data in this study were obtained using pressure transducer and visualization by video camera and recorded at multiple angles of attack (0o,15o and 25o) and different Water discharge (l/min) (20, 25, 35 and 45) and different air discharge (l/min) (10, 20, 30 and 40).
When (α=0°) the flow is parallel to the hydrofoil surface and there is no vortex shedding behind the hydrofoil.
When (α=15°) the flow separates from the upper-surface and the separation point moves towards the leading edge of the hydrofoil as the air water discharges increases.
When the angle of hydrofoil (α=25°), the flow separates near the leading edge of the upper surface and large eddies are shed from both the upper and lower surfaces.
For constant water discharge, the pressure difference increased with increased air discharge with the same angle of hydrofoil
