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.
