设计一种波浪驱动的顶铰摆式掺气装置。通过物理模型试验方法,研究规则波作用下入射波高、波周期及静水深对该装置的水动力和掺气行为的影响。研究结果表明,随着入射波高从0.06 m增至0.10 m,顶铰摆平均纵摇角幅度最大增幅达51.9%,装置平均掺气流量最大增幅达142.2%。随着入射波周期的增加,装置掺气流量呈先增加后减小的趋势;当入射波周期为3.2 s时,装置掺气流量达到最大值2.01 L/min。
Abstract
A top-hinged flap-type aeration device was designed. The effects of incident wave height, wave period and still water depth on hydrodynamic and aeration behaviors of the device were experimentally investigated under regular waves. The results show that with the increase of incident wave height from 0.06 m to 0.10 m, the maximum amplification of average pitch angle amplitude of the top-hinged flap is 51.9%, and the maximum amplification of the device's average aeration flow rate is 142.2%. With the increase of incident wave period, the aeration flow rate of the device increases at first and then decreases. When the incident wave period is 3.2 s, the aeration flow rate reaches the maximum value of 2.01 L/min.
