Patent ID: 8262316

Claim:
A wave generator for a pool of water defined by a channel having a side wall, the wave generator comprising: one or more foils, each foil arranged vertically along at least a major part of the side wall and adapted for movement in a direction along a length of the side wall, each foil having a curvilinear cross-sectional geometry that defines a leading surface that is concave about a vertical axis to generate a primary wave in the water from the movement, and a trailing surface for flow recovery behind the primary wave to avoid separation of the flow of water along the foil and to mitigate drag on the foil from the movement, the trailing surface narrowing from a maximum width of the foil adjacent the leading surface to a point at an end of the foil; and a moving mechanism connected with the one or more foils for moving the one or more foils in the direction along the length of the side wall to generate a surface gravity wave by each of the one or more foils.
