Wave generating system

a technology of generating system and generating system, which is applied in the direction of non-positive displacement fluid engine, bath, non-positive displacement pump, etc., can solve the problems of inefficiency of releasing excess compressed air that produces inferior waves, small volume of pressurized air needed to achieve such effective operation in many embodiments, and inefficient release of excess compressed air, etc., to reduce or mitigate the effect of low pressure within the chamber

Abstract

An improved device for discharging water that is capable of efficiently generating an effective wave-like motion within a body of water. Wave generation devices based on water filled elongated tubular chambers having a substantially closed rear end and a substantially open front end and using compressed air to discharge water, such as the wave cannon, may experience operational inefficiencies from variations in quantities of compressed air. Reducing the quantity of compressed gas may result in ineffective waves and damage to the elongated tube as internal low pressure conditions collapse. A source of make-up fluid configured to mitigate internal low pressure conditions can enable effective wave generation with reduced quantities of compressed air.
