Bounds on double-diffusive convection [PDF]
We consider double-diffusive convection between two parallel plates and compute bounds on the flux of the unstably stratified species using the background method. The bound on the heat flux for Rayleigh–Bénard convection also serves as a bound on the double-diffusive problem (with the thermal Rayleigh number equal to that of the unstably stratified ...

Triply Resonant Double Diffusive Convection in a Fluid Layer
We study the problem of double-diffusive convection in a horizontal plane fluid layer when there is a heat sink/source which is linear in the vertical coordinate which is in the opposite direction to gravity.

The effect of temperature-dependent solubility on the onset of thermosolutal convection in a horizontal porous layer [PDF]
We consider the onset of thermosolutal (double-diffusive) convection of a binary fluid in a horizontal porous layer subject to fixed temperatures and chemical equilibrium on the bounding surfaces, in the case when the solubility of the dissolved ...

Numerical analysis of the influence of tilt on natural convection in a double diffusive system within a square cavity containing a thermo-dependent Carreau fluid [PDF]
This study examines the role of tilt in the temperature-dependent, double-diffusive natural convection process occurring in a tilted square cavity filled with a non-Newtonian Carreau fluid.

The double-diffusive convection is a significant physical phenomenon that arises in fluid mechanics. It is primarily associated with a convection process in which two dissimilar density gradients with varying diffusion rates are considered.

Double-diffusive instabilities of a shear-generated magnetic layer [PDF]
Previous theoretical work has speculated about the existence of double-diffusive magnetic buoyancy instabilities of a dynamically evolving horizontal magnetic layer generated by the interaction of forced vertically sheared velocity and a background ...

On a Five-Dimensional Chaotic System Arising from Double-Diffusive Convection in a Fluid Layer
A chaotic system arising from double-diffusive convection in a fluid layer is investigated in this paper based on the theory of dynamical systems. A five-dimensional model of chaotic system is obtained using the Galerkin truncated approximation.

Magnetic buoyancy instabilities in the presence of magnetic flux pumping at the base of the solar convection zone [PDF]
We perform idealized numerical simulations of magnetic buoyancy instabilities in three dimensions, solving the equations of compressible magnetohydrodynamics in a model of the solar tachocline.
