Buoyancy-Driven Flows
Buoyancy-Driven Flows
2015/7/15
Buoyancy forces, and their interplay with pressure, inertia, and rotation, represent a key ingredient in a wide range of oceanic and atmospheric flow processes. They strongly influence global ocean ci...
Phase transitions of wax esters adjust buoyancy in diapausingCalanoides acutus
Phase transitions wax esters adjust buoyancy diapausing Calanoides acutus
2014/4/8
We study the composition and biophysical properties of wax esters extracted from the Antarctic copepod,Calanoides acutus, to explore if these factors adjust buoyancy in diapausing copepods. Levels of ...
Spontaneousa chiral parity breaking by hydromagnetic buoyancy
Spontaneousa chiral parity hydromagnetic buoyancy
2010/11/11
Evidence for a parity-breaking nature of the magnetic buoyancy instability in a stably stratified gas is reported.In the absence of rotation, no helicity is produced, but the non-helical state is foun...
Alpha effect due to buoyancy instability of a magnetic layer
magnetohydrodynamics Sun: magnetic fields Instabilities Turbulence Sun dynamo
2010/11/11
Context. 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 instabilit...
A CFD ANALYSIS OF ROOM ASPECT RATIO ON THE EFFECT OF BUOYANCY AND ROOM AIR FLOW
aspect ratio room airflow buoyancy comfort
2009/10/14
Comfort conditions in air-conditioned rooms require that temperature in the occupied zone should not vary by more than 1 °C and velocity, every where in the room, should be less than 0.15 m/s so that ...
Estimation of Uncertainty of Air Buoyancy Correction for Establishment of Primary Mass Standards
air density air buoyancy correction primary mass standard
2009/10/14
The most accurate value of air density is obtained by a calculation based on the equation using measured atmospheric parameters approved by the International Committee for Weights and Measures in 1981...
Importance of Buoyancy and Chemistry Modelling in Steady RANS Simulations of Well-Ventilated Tunnel Fires
Tunnel fire Critical ventilation velocity Buoyancy modelling Chemistry modelling Steady simulations
2009/10/10
Numerical CFD simulation results are presented for well-ventilated fires in horizontal tunnels. Simulations are performed in the framework of steady Reynolds-Averaged Navier-Stokes modelling. As a tur...
Influence of body posture and ear clearing on body buoyancy during diving
ear posture position buoyancy
2009/7/20
The amount of gas introduced into the gastrointestinal (GI) tract during diving was studied by underwater weighing. The influence of body posture and ear clearing methods was determined. Ten subjects ...
