Thermal Stratification in Lakes

Nature, 1936
EARLY in this century, Thienemann1 and Naumann2 described the physical conditions in deep freshwater lakes in the temperate zone. They found a yearly cycle of events which depended on the thermal stratification of the water. Their findings, and the conclusions they drew from them, can be summarized briefly, as follows.

DEEP RESERVOIR THERMAL STRATIFICATION MODEL1

JAWRA Journal of the American Water Resources Association, 1972
ABSTRACT. 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 ...

Thermal Stratification in the Arctic Ocean

Science, 1969
Fine scale measurements of the vertical temperature profile in an Arctic water column show the presence of several cascaded isothermal layers. Layers between the depths of 300 and 350 meters range from 2 to 10 meters in thickness, while the temperature change between adjacent layers is approximately 0.026°C.

Thermal Stratification in Spherical Tanks

Volume 1: Combined Energy Cycles, CHP, CCHP, and Smart Grids; Concentrating Solar Power, Solar Thermochemistry and Thermal Energy Storage; Geothermal, Ocean, and Emerging Energy Technologies; Hydrogen Energy Technologies; Low/Zero Emission Power Plants and Carbon Sequestration; Photovoltaics; Wind Energy Systems and Technologies, 2014
Spherical tanks have the potential for cost reduction in sensible thermal energy storage (TES) systems, by using less tank building material and insulation. The current CFD study compares the Thermal Efficiency (TE) of a thermocline storage system in a spherical tank to a cylindrical tank of the same volume.

Indoor thermal stratification and its statistical distribution

Indoor Air, 2018
Thermal 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 ...

Ratcheting due to Thermal Stratification

Volume 1: Codes and Standards, 2019
Abstract Thermal ratcheting is required to be checked by most of the piping design codes, specifically the ASME B&PV Code. For cases where the variation of temperature distribution is not uniform, the existing ratchet check methodology for piping is inadequate and therefore the finite element analysis (FEA) is often used to perform ...

Thermal Plume and Stratification

2011
Visualization by synthetic schlieren of the filling box process with fluid heated by a thermal source located on the floor. A constant power of 73 W is released in a 25 cm tall, closed, insulated box filled with water. The initial temperature of the fluid is uniform and equal to the environment.

Thermal stratification in retention ponds

2005
Retention 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 ...
