Thermal Stratification Prediction at Lake Trevallyn
2017Thermal stratification refers to difference of temperature across water column and can act as a proxy of algal bloom. Algal bloom is a problem in Lake Trevallyn in Launceston, Tasmania. Administrators are interested in finding the causes of algal bloom and in prediction of such events in Lake Trevallyn.

On thermal stratification in stagnant lakes
International Journal of Engineering Science, 1980Abstract Exact analytical solutions have been found for the vertical temperature distribution in a stagnant lake or tank, subject to surface heating, for a variety boundary and initial conditions. The propagation of heat has been assumed to be due solely to molecular diffusion, convection and eddy viscosity being neglected.

Indoor thermal stratification and its statistical distribution
Indoor Air, 2018Thermal stratification is established when warmer air rises and cooler air descends under thermal buoyancy. It occurs in indoor environment situations including large warehouse-type buildings, buoyancy-driven ventilated spaces with displacement, underfloor ventilation, and/or natural ventilation, and enclosure fires with hot smoke layer on top of cold ...

Thermals with background rotation and stratification
Journal of Fluid Mechanics, 1994Scaling analysis and experiments are used to study the evolution of thermals in the presence of background rotation. When the ambient environment is homogeneous, the thermal rises and expands until it reaches a critical height where the Rossby number becomes ∼ 1. The thermal then stops expanding and rises in a column.

Thermal stratification in retention ponds
2005Retention ponds are widely used for runoff control. In France, they are particularly numerous in recent urbanised areas. They are characterised by an area around 1ha and a depth ranging from two to four or five meters. The temperature vertical structure of two such ponds, located in the Paris suburb, was monitored continuously over a 1 month and a10 ...

On thermal stratification in large bodies of water
Water Resources Research, 1974A method of predicting water temperature in large bodies of water has been presented in this paper. The vertical water column is subdivided into two layers: an isothermal surface layer and a temperature‐stratified diffusion layer. Meteorological data, either real or imposed, are used for calculating the variation of water temperature with time in the ...

Effect of cyanobacterial blooms on thermal stratification
Limnology, 2000Enclosure experiments were performed at Akanoi Bay, Lake Biwa, in 1995 to determine whether the blooms of cyanobacterial algae changed thermal stratification in the lake. We used four rectangular enclosures, each 10 m × 10 m, with a volume of 200 m3, which were open to the sediments.

DEEP RESERVOIR THERMAL STRATIFICATION MODEL1
JAWRA Journal of the American Water Resources Association, 1972ABSTRACT. A method of predicting reservoir temperature profiles is presented. The model requires monthly averaged meteorological and hydrological data along with reservoir physical characteristics. The one‐dimensional profiles are predicted by solving the time‐dependent energy equation with an assumed epilimnetic depth and a diffusion coefficient ...

The DCS Thermal Stratification Tank
1986Thermal stratification (thermocline) tanks allow storage of energy at different temperatures by taking advantage of the thermal characteristics of a fluid. The benefits of a stratification tank can be shown by its use in the DCS plant: Using only one tank, two different temperatures are available, feeding the fields with low-temperature oil from ...
