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…
Dynamics of fingering convection I: Small-scale fluxes and large-scale instabilities
A. Traxler, S. Stellmach, P. Garaud +2
Double-diffusive instabilities are often invoked to explain enhanced transport in stably-stratified fluids. The most-studied natural manifestation of this process, fingering convec…
