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

Optimal Spacings for Mixed Convection

Journal of Heat Transfer, 2004
This paper completes the description of geometry optimization in stacks of parallel plates that generate heat. The spacing between plates, or the number of plates in a fixed volume, has been maximized in two limits: pure natural convection and pure forced convection. In this paper, the in-between regime of mixed convection is modeled numerically. After

Convective Overshooting and Mixing in Stellar Evolution

Astrophysics and Space Science, 1998
Stars are a major constituent of the Universe. They provide the basic measurements of masses, distances and ages. Stars axe the sites of nuclear reactions and the origin of the elements; they determine the chemical and hence luminosity evolution of galaxies.

Mixed convection wall plumes

International Journal of Heat and Mass Transfer, 1987
Abstract A proper mixed convection parameter ζ = (σ Ra) 1 5 (ω Re) 1 2 , with σ = Pr (1 + Pr) and ω = Pr (1 + Pr) 1 3 , is proposed to replace the conventional parameters, Gr Re 5 2 and Re Gr 2 5 , for the analysis of mixed convection wall plumes.

Convective Overshooting and Mixing

1997
Convection is of major importance in both energy transport and mixing in stars. Convective penetration, or overshooting from unstable into the surrounding stable layers, extends the zone of effective mixing influencing both the thermal structure and evolution of stars.

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 ...

Mixed Convection on Inclined Surfaces

Journal of Heat Transfer, 1979
An analysis is performed to study the effects of buoyancy force on the heat transfer characteristics of laminar forced convection flow over an inclined flat surface which is either maintained at a uniform temperature or subjected to a uniform heat flux.

Mixed Convection in Multicomponent Systems

1984
We have been interested in the study of transport phenomena in liquid phase for a long time. These phenomena are rather well understood in the gas phase, and the kinetic theory of gases predicts, more or less correctly, the experimental values of transport coefficients such as the viscosity and the isothermal diffusion coefficient, and even coupled ...
