Abstract:
This study aims to improve the design factors of air diffuser systems that have been analyzed in laboratory experiments, with consideration of the field conditions of dam reservoirs. In this study, the destratification number (DN), destratification radius, and efficiency are considered as design factors. The computational fluid dynamics (CFD) simulation experiment is performed in diverse field conditions in order to analyze these factors. The results illustrate the wider range of DN values in field conditions and the relationship of the destratification radius and efficiency to DN. The results

Abstract:
An experimental study of transient destratification in a rectangular air-filled enclosure is described. The test cell, which is 1 m high, 0.5 m wide, and 0.25 m deep, is made of plexiglass with a variety of side and bottom thermal boundary conditions. The initial vertical stratification is 30°C. A number of transient tests are reported in which a destabilizing heat source is introduced after the initial stratification. Temperature maps of the middepth plane are recorded and analyzed. Basic enclosure destratification dynamics are described in terms of developing thermal and flow fields. Separat

Abstract:
In May 1994 an artificial destratification system was installed at the eutrophic 27,200ML Hanningfield raw water reservoir in Essex U.K. The main objective of this installation was to prevent poor raw water quality, which can result from hypolimnetic isolation in the Summer months when thermal stratification often occurs. By adopting an intermittent destratification strategy to constantly change reservoir conditions thus promoting competition amongst algae, it is hoped that an overall decrease in annual phytoplankton biomass at the reservoir will result. This in turn will reduce the pressure o

Abstract:
Two important bubbler-performance criteria, the mechanical efficiency, ηmech, and the destratification time, Γ, were analysed as functions of two dimensionless parameters, G, the strength of stratification, and M, the source strength. Equations to estimate the optimum airflow rate (via M) and corresponding ηmech and Γ for a known linear stratification G in a reservoir were derived. Owing to difficulties in accurately determining the actual G, it was demonstrated that it is appropriate practice to reduce the design G value by around 10%. It was shown that the equivalent linear stratification me

Abstract:
Artificial thermal mixing of the water column is a common method of addressing water quality problems with the most popular method of destratification being the bubble curtain. The air or oxygen distribution along submerged multiport diffusers is based on similar basic principles as those of outfall disposal systems. Moreover, the disposal of sequestered greenhouse gases into the ocean, as recently proposed by several researchers to mitigate the global warming problem, requires analogous design criteria.

Abstract:
Explanations of the glacial–interglacial variations in atmospheric pCO2 invoke a significant role for the deep ocean in the storage of CO2. Deep-ocean density stratification has been proposed as a mechanism to promote the storage of CO2 in the deep ocean during glacial times. A wealth of proxy data supports the presence of a “chemical divide” between intermediate and deep water in the glacial Atlantic Ocean, which indirectly points to an increase in deep-ocean density stratification. However, direct observational evidence of changes in the primary controls of ocean density stratification, i.e.

Abstract:
Destratification in the York River, USA, during high spring tides is the result of the interruption of normal two-layer estuarine flow by advection of relatively fresh water in to the River mouth from the Chesapeake Bay. This is due to the presence of a longitudinal salinity gradient in the Bay and a difference of tidal current phase between the River and the Bay. Similar behavior is seen in other subestuaries of the Chesapeake Bay and may be common in subestuary-estuary interactions. Correlation and regression analysis are used to examine relationships between stratification variation in the

Aeration is one of ecological preventive methods to prevent growth of cyanobacteria. Increase of dissolved oxygen content in water mass leads to support of the growth of organisms which are disadvantaged by impossibility of movement in water mass and thus also to support biodiversity. Given biodiversity has a positive effect on water quality because it avoids the outbreak of one species of aquatic organism, in particular of cyanobacteria. Designed aeration equipment uses mem

In the summer, air is supplied low and returned just above the occupied zone in order to cool the occupied zone directly, letting the upper zone stratify.

During the last decades, the so-called two-fluid model has been the most widely used in two-phase flow studies for environmental and industrial applications. In this model, one set of mass, momentum and energy balance equations is written for each phase, therefore the model is able to deal with mechanical and thermal imbalances. The two phases cannot evolve independently, since they are coupled together through interfacial interaction terms representing the average exchanges between the two phases. The success of the two-fluid model in particular situations strongly depends on the modeling of
