Effects of water level fluctuation on thermal stratification in a typical tributary bay of Three Gorges Reservoir, China [PDF]

open access: yesPeerJ, 2019
Xiangxi River is a typical tributary of Three Gorges Reservoir (TGR) in China. Based on field observations in 2010, thermal stratification was significant in most months of the year. Through field data analysis and numerical simulations, the seasonal and

Thermal conductivity of Fe-Si alloys and thermal stratification in Earth's core. [PDF]

open access: yesProc Natl Acad Sci U S A, 2022
Significance Earth’s liquid outer core is mainly composed of iron alloyed with ∼8 to 10% of light elements (e.g., silicon). Convection of the liquid core generates Earth’s magnetic field, which is controlled by the thermal conductivity of the core.

Modeling Thermal Stratification in Aquaculture Ponds

open access: yesAsian Fisheries Science, 2000
A stratification model was developed for the simulation of the temporal and spatial variation of temperature in aquaculture ponds. A new parameter, called the fish turbulent diffusivity, was incorporated in the equation to calculate the ...

Characteristics and driving factors of thermal stratification evolution in Daheiting Reservoir [PDF]

open access: yesE3S Web of Conferences, 2021
Thermal stratification which is common in water bodies is subject to such factors as the water depth of the water body (a lake or reservoir, for instance), the fluidity of the water and the local meteorological conditions.

Development of reduced-order thermal stratification model for upper plenum of a lead–bismuth fast reactor based on CFD

open access: yesNuclear Engineering and Technology, 2023
After an emergency shutdown of a lead-bismuth fast reactor, thermal stratification occurs in the upper Plenum, which negatively impacts the integrity of the reactor structure and the residual heat removal capacity of natural circulation flow.
