Abstract:
A device for making surfable standing wave, said device comprising:a flume having side wall for containing a flow of water;water flow means for providing a flow of water flowing along said flume in a first direction;a water-shaping aerofoil structure disposed within said flume, said structure having a top surface, a bottom surface substantially opposite said top surface, a leading edge, and a trailing edge, said aerofoil structure being disposed within said flume such that a flow of water provided by said water flow means contacts and flows across the top surface and the bottom surface of said aerofoil structure, is shaped by said structure, and flows substantially in a direction from said leading edge toward said trailing edge; andwave-forming means disposed downstream of said aerofoil structure within said flume and said wave-forming means comprising a wave-forming surface for forming a flow of water provided by said wave flow means into a surfable wave after the flow has been shaped by said aerofoil structure, said wave-forming surface having a lower front edge portion and an upper front edge portion, wherein the lower front edge portion is in closer proximity to the trailing edge of said aerofoil structure than is said upper front edge portion so that a flow of water flowing down said flume travels from the lower front edge portion of said wave-forming surface up and over said upper front edge portion and forms a surfable wave.
