The lightness of water vapor helps to stabilize tropical climate. [PDF]

open access: yes, 2020
Moist air is lighter than dry air at the same temperature, pressure, and volume because the molecular weight of water is less than that of dry air. We call this the vapor buoyancy effect.

Alpha effect due to buoyancy instability of a magnetic layer [PDF]

open access: yes, 2010
A strong toroidal field can exist in form of a magnetic layer in the overshoot region below the solar convection zone. This motivates a more detailed study of the magnetic buoyancy instability with rotation.

Heat transfer of a buoyancy-aided turbulent flow in a trapezoidal annulus [PDF]

open access: yes, 2017
The objective of this paper is to report a numerical investigation into the heat transfer of a buoyancy-aided flow in a rod-bundle-like channel. The flow field is simulated using large eddy simulation (LES) with WALE SGS model and the buoyant force is ...

The Mediation Role of Meaning of Life in Relationship between Family Cohesion and Family Flexibility with Academic Buoyancy [PDF]

open access: yesپژوهشنامه روانشناسی مثبت, 2019
The aim of this study was the assessment of mediating role of the meaning of life (including two subscales: Presence of Meaning and Search for Meaning) between family cohesion and family flexibility and academic buoyancy.

Influence of friction on granular segregation [PDF]

open access: yes, 2007
Vertical shaking of a mixture of small and large beads can lead to segregation where the large beads either accumulate at the top of the sample, the so called Brazil Nut effect (BNE), or at the bottom, the Reverse Brazil Nut effect (RBNE).

Enhanced Thermal Efficiency Using Hybrid Nanofluids in MHD Boundary Layer Flow: Buoyancy and Entropy Perspective [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences
The growing relevance of hybrid nanofluids (HNFs) in advanced thermal management systems has driven extensive research in recent years. Nevertheless, the cumulative effects of thermal and solutal buoyancy, MHD, viscous dissipation, and Newtonian heating ...
