Abstract

Aeration and reoxygenation is the significant source of the dissolved oxygen for spillway discharge. Due to the strong turbulence, large numbers of bubbles are entrained into the water, which causes the supersaturation of dissolved gas concentration and leads to bubble disease of fish. Firstly, the theory of the aeration and reoxygenation for spillway discharge is analyzed base on the mass transfer theory of water-air interface and the bubble interface. Secondly, the convection and diffusion equation of dissolved oxygen and the method of parameter selection are discussed. Finally, the progress and shortage of the present study are analyzed.
