Secondary flows in statistically unstable turbulent boundary layers with spanwise heterogeneous roughness

open access: yesTheoretical and Applied Mechanics Letters, 2022
Large-scale secondary motions are known to occur in turbulent flows over surfaces with spanwise roughness heterogeneity. Numerical studies often use adjacent high- and low-roughness longitudinal strips to investigate these secondary rolls in boundary ...

The Evaluation of Thermal Stratification by Exergy [PDF]

open access: yes, 1989
What makes a good heat store? Is it a large store, with a large volume? And is the largest the best? We experienced this question when the first solar houses were built: many stores were oversized and never reached temperatures high enough for heating.

Thermal Stratification in the Storage Tank

open access: yesProcedia Manufacturing, 2020
Abstract The paper presents the results of the numerical investigation of the thermal stratification occurring in the three-coil heat exchanger creating the hot water storage tank. The heat exchanger considered is a special type of coiled tube exchanger which can recover the waste heat from air conditioning system.

Moist Convection and the Thermal Stratification of the Extratropical Troposphere [PDF]

open access: yes, 2008
Simulations with an aquaplanet general circulation model show that sensible and latent heat transport by large-scale eddies influences the extratropical thermal stratification over a wide range of climates, even in relatively warm climates with small ...

Chemical and thermal stratification in lakes [PDF]

open access: yesLimnology, 2010
An index that shows chemical stratification strength [IC-i; i = water quality item such as chlorophyll-a (Chl.a) and soluble phosphorus (SP)] was proposed and compared with one of thermal stratification strength indices, Schmidt’s stability index (SSI), in Shiozu Bay and Lake Biwa, Japan.
