Nonlinear double-diffusive convection

Journal of Fluid Mechanics, 1976
The two-dimensional motion of a fluid confined between two long horizontal planes, heated and salted from below, is examined. By a combination of perturbation analysis and direct numerical solution of the governing equations, the possible forms of large-amplitude motion are traced out as a function of the four non-dimensional parameters which specify ...

Double-diffusive convection with sidewalls

The Physics of Fluids, 1985
The effect of rigid vertical boundaries on the onset of convective instability is calculated for the salt finger regime of double-diffusive convection. The unperturbed state is a quiescent fluid with constant vertical gradients of temperature and solute, which are stabilizing and destabilizing, respectively.

Double-diffusive Marangoni convection in a rectangular cavity: Onset of convection

Physics of Fluids, 2010
Double-diffusive Marangoni convection in a rectangular cavity with horizontal temperature and concentration gradients is considered. Attention is restricted to the case where the opposing thermal and solutal Marangoni effects are of equal magnitude (solutal to thermal Marangoni number ratio Rσ=−1). In this case a no-flow equilibrium solution exists and

Intrusions and double-diffusive convection

Nature, 1976
A STRATIFIED fluid layer in which two components contribute to the vertical density distribution need not be stable even though the net density decreases upwards. If one of the components is unstably distributed, then molecular diffusion can release its potential energy—a phenomenon known as double-diffusion convection1.

Soret and Double Diffusive Convection in a Porous Cavity

Journal of Porous Media, 2004
Summary: Natural convection in a rectangular porous medium filled with a binary fluid is studied analytically and numerically. The two vertical walls of the cavity are subject to constant gradients of temperature while the two horizontal ones are adiabatic and impermeable. Solutal gradients are assumed to be induced either by the imposition of constant

Penetrative double-diffusive convection

The Physics of Fluids, 1987
The onset of double-diffusive convection is studied for an infinite fluid layer possessing a density maximum in its interior. Linear stability analyses are performed on a basic state with constant temperature and concentration gradients in which the density-temperature relationship is quadratic.

Transitions in double-diffusive convection

Nature, 1976
The transitions of solutions of differential equations from one stability regime to another are of great current interest, both mathematical and physical, and there are conflicting hypotheses as to how such transitions occur. Here we present the results of an investigation of double-diffusive convection, which is important in oceanography, astrophysics

DRBEM Solution of the Double Diffusive Convective Flow

2016
A numerical investigation of unsteady, two-dimensional double diffusive convection flow through a lid-driven square enclosure is carried on. The left and bottom walls of the enclosure are either uniformly or non-uniformly heated and concentrated, while the right vertical wall is maintained at a constant cold temperature.

Double Diffusive Convection with LTNE

2015
In the standard Bnard problem the instability is driven by a density difference caused by a temperature difference between the upper and lower planes bounding the fluid. If the fluid layer additionally has salt dissolved in it then there are potentially two destabilizing sources for the density difference, the temperature field and the salt field.
