Three-dimensional spatially localized binary-fluid convection in a porous medium [PDF]
, 2013 Three-dimensional convection in a binary mixture in a porous medium heated from below is studied. For negative separation ratios steady spatially localized convection patterns are expected.

Unsteady Meshfree Framework for Double-diffusive Natural Convection with Boundary and Geometry Effects [PDF]
Journal of Applied and Computational MechanicsIn this study, a meshfree framework based on the reproducing kernel collocation method is proposed for incremental-iterative analysis of double-diffusive natural convection in a porous enclosure, in which the forward difference method is adopted for ...

A theoretical model for double diffusive phenomena in cloudy convection [PDF]
Annales Geophysicae, 2003 Using classical rheological principles, a model is proposed to depict the molecular diffusion in a moist-saturated dissipative atmosphere: due to the saturation condition existing between water vapor and liquid water in the medium, the equations ...

Blue Sky Catastrophe in Double-Diffusive Convection [PDF]
Physical Review Letters, 2004 A global bifurcation of the blue sky catastrophe type has been found in a small Prandtl number binary mixture contained in a laterally heated cavity. The system has been studied numerically applying the tools of bifurcation theory. The catastrophe corresponds to the destruction of an orbit which, for a large range of Rayleigh numbers, is the only ...

Maxwell-Cattaneo double diffusive convection: limiting cases [PDF]
, 2021 Double-diffusive convection, in which a fluid is acted upon by two fields (such as temperature and salinity) that affect the density, has been widely studied in areas as diverse as the oceans and stellar atmospheres.

Triply Resonant Double Diffusive Convection in a Fluid Layer
Mathematical Modelling and Analysis, 2017 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.

Bounds on double-diffusive convection [PDF]
Journal of Fluid Mechanics, 2006 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 ...

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]
EPJ Web of ConferencesThis 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.
