Convectively mixed humidity chamber

Review of Scientific Instruments, 1977
A humidity chamber is described, based on the principle of thermodynamically regulated (vapor pressure) control, in which the attainment of thermodynamic equilibrium is enhanced by gentle convective stirring. It may be used as a chamber which maintains constant dew point while allowing variation of the temperature of the test section, or the test ...

REGARDS ON MIXED CONVECTION

Proceeding of Proceedings of CONV-14: International Symposium on Convective Heat and Mass Transfer. June 8 - 13, 2014, Kusadasi, Turkey, 2014
This lecture aims to place again the mixed thermal convection in the center of the convection heat transfer and to emphasize three issues that arise by this approach: (i) a clear definition of the reference temperature in the Boussinesq approximation; (ii) a practical delimitation of the three convective modes, which are the forced convection (FC ...

MHD mixed convection of nanofluid in a three-dimensional vented cavity with surface corrugation and inner rotating cylinder

International journal of numerical methods for heat & fluid flow, 2019
Purpose This study aims to numerically examine mixed convection of CuO-water nanofluid in a three-dimensional (3D) vented cavity with inlet and outlet ports under the influence of an inner rotating circular cylinder, homogeneous magnetic field and ...

Thermal nonlinear oscillator in mixed convection

Physical Review E, 2011
A detailed numerical simulation is carried out for transient laminar flow opposing mixed convection in a downward vertical channel flow with both walls suddenly subjected to isothermal heat sources over a finite portion of the channel walls, by solving the unsteady two-dimensional Navier-Stokes and energy equations. The dynamical behavior of the system

MIXED CONVECTION AT A STAGNATION POINT

The Quarterly Journal of Mechanics and Applied Mathematics, 1995
Summary: We are concerned with the mixed convective flow at a two-dimensional stagnation point on a heated horizontal boundary. The forced flow may be a stagnation-point flow of either forward or rear type, and the free convective element is due to a pressure gradient that is induced by temperature variations along the boundary.

Mixed convection and stability analysis of stagnation-point boundary layer flow and heat transfer of hybrid nanofluids over a vertical plate

, 2019
This study aims to study the mixed convection flow and heat transfer of Al2O3-Cu/water hybrid nanofluid over a vertical plate. Governing equations for conservation of mass, momentum and energy for the hybrid nanofluid over a vertical flat plate are ...

Convective versus absolute instability in mixed Rayleigh–Bénard–Poiseuille convection

Journal of Fluid Mechanics, 1999
Transition from convective to absolute instability in Rayleigh–Bénard convection in the presence of a uni-directional Poiseuille flow is studied. The evaluation of the long-time behaviour of the Green function in the horizontal plane allows the determination of regions of convective and absolute instability in the Rayleigh–Reynolds number plane ...

Magma mixing by convective entrainment

Nature, 1996
RECENT studies of volcanic eruptions have brought to light a puzzling sequence: the ejection of dense and mixed liquids followed by a larger volume of unmixed, less dense liquid1–4. Although these studies have shown that the mixing is associated with the injection of basaltic liquid into a more silicic magma chamber, a paradox remains.

Convective Mixed Layer

1988
Buoyancy is the dominant mechanism driving turbulence in a convective boundary layer. Such turbulence is not completely random, but is often organized into identifiable structures such as thermals and plumes (Young, 1988). Entertainment happens at a variety of scales: lateral entertainment by small eddies into the sides of thermals, and vertical ...
