| Abstract |
This study deals with a proposed scheme for restoration and maintenance of dissolved oxygen in the hypolimnion of stratified impoundments without disturbing the stratification. The characteristics of a bubble-water plume, as used in hypolimnion aeration, were studied. The major factor introduced in the study of these characteristics was the effect of mass transfer. A mathematical model was developed for this case and compared with a mathematical model which neglects the effect of mass transfer. The model calculates the diameter of the bubble, the diameter of the plume, the velocity of plume rise, the water flow rate, and the momentum and energy flux for the rising plume at any level above the diffuser. It also calculates the amount of oxygen absorbed at any level and the increase of the dissolved oxygen concentration in the plume for any oxygen flow rate. (Modified author abstract) |
