A numerical model that simulates the destratification of a lake/reservoir by an
air bubble column/point diffuser is presented. In the numerical model, the
lakeLreservoir is divided into a nearfield and a farfield. The nearfield model includes
the bubble plume and the flow in its vicinity. The farfield model treats the rest of
the lake and considers the flow from the plume toward the lake and from the lake
toward the plume. The mixing model is combined with multilayer dynamic
stratification models WESTEX and CE-QUAL-R1 by the U.S. Army Corps of
Engineers Waterways Experiment Station, to account for heat transfer through the
water surface and other processes in the lake/reservoir during the mixing induced by
the release of the air bubbles.
