Development of air-lifted artificial upwelling powered by wave

摘要: This paper presents that an artificial upwelling system integrated with air-lift tube and wave powered air booster. The flow had proved the air-water mixture upward in immersed water can make underwater at bottom too. introduces power to collect pump into one depth of tube. Meanwhile deep far from continent, nutrition concentration near seabed is higher than surface sea. On contrary, oxygen less on top. available method balance or decrease difference characters between sea, which improve environment marine ranching, promote growth biological food chain. One project - air-lifted by been applied carried on. In order confirm efficiency, 2 lake experiments were finished Qiandao Lake, first experiment was done directly a plastic hose, while second experiment, made tensional cloth supported steel supporting rings, these showed efficiency hose shrinkage deformation happens easily case large flow. addition, simulation platform designed numerical simulated, simulate lifting dropping buoyant ball then get compressed air, whose aim performance collecting compressing capacity hydraulic power.
