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 ...

Estimation of ice shelf melt rate in the presence of a thermohaline staircase [PDF]
, 2015 Diffusive convection–favorable thermohaline staircases are observed directly beneath George VI Ice Shelf, Antarctica. A thermohaline staircase is one of the most pronounced manifestations of double-diffusive convection.

Semiconvection: numerical simulations [PDF]
, 2013 A grid of numerical simulations of double-diffusive convection is presented for the astrophysical case where viscosity (Prandtl number Pr) and solute diffusivity (Lewis number Le) are much smaller than the thermal diffusivity.

Double‐diffusive convection in Lake Kivu [PDF]
Limnology and Oceanography, 2009 Double‐diffusive staircases with a total of 230‐350 mixed layers and sharp interfaces were observed in nine microstructure temperature profiles measured during February 2004 in Lake Kivu. The presence of these staircases at depths > 120 m indicates that diapycnal turbulent mixing is weak and vertical diffusive transport is dominated by double ...

Double-diffusive erosion of the core of Jupiter [PDF]
, 2017 We present Direct Numerical Simulations of the transport of heat and heavy elements across a double-diffusive interface or a double-diffusive staircase, in conditions that are close to those one may expect to find near the boundary between the heavy ...

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 ...

Simulations of stellar convection, pulsation and semiconvection [PDF]
, 2010 We report on modelling in stellar astrophysics with the ANTARES code. First, we describe properties of turbulence in solar granulation as seen in high-resolution calculations.

Dynamics of fingering convection I: Small-scale fluxes and large-scale instabilities [PDF]
, 2010 Double-diffusive instabilities are often invoked to explain enhanced transport in stably-stratified fluids. The most-studied natural manifestation of this process, fingering convection, commonly occurs in the ocean's thermocline and typically increases ...
