Experimental study of the surface wave around hydrofoils
To study the surface wave profile and surface waves evolution around different hydrofoils, an experimental rig was built based on a water tunnel platform. Different hydrofoils were adopted respectively in transparent experimental part of the flow system. High speed photography was applied in the experiment to record the instant variation of the waves profile. The results show that:(1) under the action of boundary layer, two separated wave filaments appear when the surface wave deviates from the hydrofoils surface; (2) the travel velocity of the wave separating from the leading edge is obviously larger that that of the wave separating from the trailing edge; (3) the consequence of wave-wave action is the occurrence of wake vortex element which remains its shape for a relative long period.
