Lake Destratification by Bubble‐Plume Systems: Design Methodology

Abstract

Thermal stratification during summer may result in lowered dissolved‐oxygen levels below the thermocline of lakes and reservoirs. To avoid further deterioration of water quality, artificial destratification has long been practiced. This paper presents a totally new design methodology for the design of bubble‐plume destratification systems. It is based on the interaction that occurs between a buoyant bubble plume and the density stratified water column through which it rises. Two dimensionless parameters,
