Buoyancy effects in a solar regenerator

Solar Energy, 1979
Abstract In laminar forced solar regenerator the temperature of absorbent solution is different from that of the air passing over it and on account of low velocities used buoyancy forces are always present. This paper deals with the theoretical investigations of first order deviation of heat and mass transfer rates due to the buoyancy effect.

Buoyancy effects on smoldering combustion

Acta Astronautica, 1986
The effect of buoyancy on the rate of spread of a concurrent smolder reaction through a porous combustible material is investigated theoretically and experimentally. In the experiments, buoyant forces are controlled by varying the density difference, and the smolder rate spread through porous alpha cellulose (0.83 void fraction) is measured as a ...

Effect of Buoyancy on Transverse Mixing in Streams

Journal of Hydraulic Engineering, 1990
A dye tracer study has been conducted in a large recirculating flume for the purpose of examining the influence of buoyancy on transverse mixing in streams. Using Rhodamine WT dye, the transverse spread of a freshwater discharge into a saline receiving stream was measured downstream from the release point.

An Analytical Solution of the Effective-Buoyancy Equation

Journal of the Atmospheric Sciences, 2022
Abstract The effective buoyancy per unit volume is the statically forced part of the local nonhydrostatic upward pressure-gradient force. It is important because it does not depend on the basic-state density defined with the anelastic approximation. Herein, an analytical solution is obtained for the effective buoyancy associated with an axisymmetric ...

Effect of Buoyancy on Room Air Flow

Volume 2, Parts A and B, 2004
Thermal comfort and ventilation needs of spaces are met by supplying “conditioned” air, which is a blend of outdoor and recirculated air that has been filtered, heated or cooled, and sometimes humidified or dehumidified. Comfort conditions in air-conditioned rooms require that temperature in the occupied zone should not vary by more than 1°C and ...

Buoyancy Effects on Natural Ventilation

2013
This book describes in depth the fundamental effects of buoyancy, a key force in driving air and transporting heat and pollutants around the interior of a building. This book is essential reading for anyone involved in the design and operation of modern sustainable, energy-efficient buildings, whether a student, researcher or practitioner.

Buoyancy effects on laminar impinging jets

International Journal of Heat and Mass Transfer, 1988
Abstract A laminar, heated, two-dimensional jet impinging on an isothermal surface has been studied to determine the effects of buoyancy on the flow and thermal structure of the region near impingement. The parameters used include the jet exit Reynolds number, Richardson number, and separation distance between the impinging surface and the jet exit ...

The Effect of Buoyancy on Flickering in Diffusion Flames

Combustion Science and Technology, 1997
Flame flickering of jet diffusion flames reflects the instability of the hot gases ascending column, This phenomenon, which is related to buoyancy, has been characterized in terms of pressure and gravitational force by experiments conducted on the ground and on board of an aircraft.

Buoyancy Effects in Complex Jet Flows

Heat Transfer and Fluids Engineering, 1995
Abstract Flow visualization and mean vorticity measurements for a variety of buoyant jets and plumes issuing in stagnant, stratified or crossflow environment are carried out. The results indicate the existence of large scale structures in all investigated flows. In the case of jets into cross-streams wake-like or jet-like structures were

Effective Buoyancy in Squall Lines

Journal of the Atmospheric Sciences
Abstract Squall lines consist of a buoyancy discontinuity with positive buoyancy extending hundreds of kilometers behind their leading edge. Because of this structure, conceptual models for isolated deep convective updrafts, which have a comparatively limited horizontal extent, fail to explain squall-line thermodynamics.
