A New Model for Mixing By Double-Diffusive Convection (Semi-Convection). III. Thermal and Compositional Transport Through Non-Layered ODDC
Ryan Moll, Pascale Garaud, Stephan Stellmach
Oscillatory double-diffusive convection (ODDC) (also known as semi- convection) refers to a type of double diffusive instability that occurs in regions of planetary and stellar int…
Anelastic Versus Fully Compressible Turbulent Rayleigh-Bénard Convection
Jan Verhoeven, Thomas Wiesehöfer, Stephan Stellmach
Numerical simulations of turbulent Rayleigh-Bénard convection in an ideal gas, using either the anelastic approximation or the fully compressible equations, are compared. Theoretic…
Double-diffusive mixing in stellar interiors in the presence of horizontal gradients
Michael Medrano, Pascale Garaud, Stephan Stellmach
We have identified an important source of mixing in stellar radiation zones, that would arise whenever two conditions are satisfied: (1) the presence of an inverse vertical composi…
Chemical Transport and Spontaneous Layer Formation in Fingering Convection in Astrophysics
Justin M. Brown, Pascale Garaud, Stephan Stellmach
A region of a star that is stable to convection according to the Ledoux criterion may nevertheless undergo additional mixing if the mean molecular weight increases with radius. Thi…
A new model for mixing by double-diffusive convection (semi-convection). II. The transport of heat and composition through layers
Toby S. Wood, Pascale Garaud, Stephan Stellmach
Regions of stellar and planetary interiors that are unstable according to the Schwarzschild criterion, but stable according to the Ledoux criterion, are subject to a form of oscill…
A new model for mixing by double-diffusive convection (semi-convection): I. The conditions for layer formation
Giovanni M. Mirouh, Pascale Garaud, Stephan Stellmach +2
The process referred to as "semi-convection" in astrophysics and "double-diffusive convection in the diffusive regime" in Earth and planetary sciences, occurs in stellar and planet…
Turbulent mixing and layer formation in double-diffusive convection: 3D numerical simulations and theory
Erica Rosenblum, Pascale Garaud, Adrienne Traxler +1
Double-diffusive convection, often referred to as semi-convection in astrophysics, occurs in thermally and compositionally stratified systems which are stable according to the Ledo…
Numerically determined transport laws for fingering ("thermohaline") convection in astrophysics
Adrienne Traxler, Pascale Garaud, Stephan Stellmach
We present the first three-dimensional simulations of fingering convection performed in a parameter regime close to the one relevant for astrophysics, and reveal the existence of s…
A model of the entropy flux and Reynolds stress in turbulent convection
Pascale Garaud, Gordon I. Ogilvie, Neil Miller +1
We propose a closure model for the transport of entropy and momentum in astrophysical turbulence, intended for application to rotating stellar convective regions. Our closure model…
