Quantifying the performance of a top-down natural ventilation Windcatcher™ [PDF]

open access: yes, 2009
Estimating the performance of a natural ventilation system is very important if one is to correctly size the system for a particular application. Estimating the performance of a Windcatcher™ is complicated by the complex flow patterns that occur during ...

The Buoyancy of the Sun-fish [PDF]

open access: yesNature, 1922
ABOUT the end of August numbers of sun-fish (Orthagoriscus mola) make their appearance off the north coast of Ireland floating passively on the surface of the sea. The positive buoyancy, while not so great as to prevent the fish from submerging when attacked, constitutes a constant upward drag which brings it back to the surface as soon as it stops ...

The Effects of Buoyancy on Laminar Heat Transfer Rates to Supercritical CO2 in Vertical Upward Flows

open access: yesFluids, 2023
Buoyancy effects in vertical, upward laminar flows can result in an augmentation in heat transfer rates to supercritical CO2 (sCO2) near its pseudocritical temperature (TPC).

Modification of k-ε Model for Sensible Heat and Momentum Flux Reconstruction from Surface Temperature Data

open access: yesAtmosphere, 2022
We present a modified k-ε model with a set of wall-functions suitable for reconstruction of sensible heat and momentum fluxes from the observations data (e.g., surface temperature evolution during the diurnal cycle).

Use of cryogenic buoyancy systems for controlled removal of heavy objects from the seabed

open access: yes, 2009
The concept design of a lightweight cryogenic marine heavy lift buoyancy system has been investigated. The approach makes use of a novel cryogenic system for provision of buoyancy within the ocean environment. The objective is to be able to lift or lower

The Teacher Academic Buoyancy Scale: Is it possible to keep TABS on students' academic buoyancy?

open access: yesInternational Journal of Assessment Tools in Education, 2018
Academic buoyancy (AB) is the ability toovercome minor academic setbacks. However, although it seems as though teacherswould be well placed to comment on this characteristic in students, noteacher-report measure of AB exists.

Transient Dynamics in Counter-Rotating Stratified Taylor–Couette Flow

open access: yesMathematics, 2023
This study focuses on the investigation of stratified Taylor–Couette flow (STCF) using non-modal analysis, which has received relatively limited attention compared to other shear flows. The dynamics of perturbations under different temperature conditions

Sorption of petroleum products with natural sorbents

open access: yesАлматы технологиялық университетінің хабаршысы, 2021
This article presents the results of a study of cleaning the water surface from contamination with petroleum products. Kulantaussky vermiculite, the birthplace of the Turkestan region, was studied as a sorbent.

The location of diapycnal mixing and the meridional overturning circulation [PDF]

open access: yes, 2002
The large-scale consequences of diapycnal mixing location are explored using an idealized threedimensional model of buoyancy-forced flow in a single hemisphere. Diapycnal mixing is most effective in supporting a strong meridional overturning circulation (
