摘要: A wave-driven seawater pump, composed of a resonant and an exhaust duct joined by variable-volume air compression chamber, is studied. The time dependent form Bernoulli's equation, adapted to incorporate losses due friction, vortex formation at the mouths radiation damping, describes pump behaviour. dimensional analysis equations shows that proposed scale-model will perform similar full-scale pump. Fluid oscillations in ducts damped, two-mass spring system, excited waves. condition can be maintained, for different wave frequencies, varying volume chamber. basic behaviour linear its performance significantly increased optimising design mouths. Linear estimates chamber flow rate through are derived.
