Resistive instabilities in sinusoidal shear flows with a streamwise magnetic field
Adrian E. Fraser, Imogen G. Cresswell, Pascale Garaud
We investigate the linear stability of a sinusoidal shear flow with an initially uniform streamwise magnetic field in the framework of incompressible magnetohydrodynamics (MHD) wit…
Journey to the center of stars: the realm of low Prandtl number fluid dynamics
Pascale Garaud
The dynamics of fluids deep in stellar interiors is a subject that bears many similarities with geophysical fluid dynamics, with one crucial difference: the Prandtl number. The rat…
Preferential concentration by mechanically-driven turbulence in the two-fluid formalism
Sara Nasab, Pascale Garaud
Preferential concentration is thought to play a key role in promoting particle growth, which is crucial to processes such as warm rain formation in clouds, planet formation, and in…
Preferential concentration in the particle-induced convective instability
Sara Nasab, Pascale Garaud
Heavy particles in turbulent flows have been shown to accumulate in regions of high strain rate or low vorticity, a process otherwise known as preferential concentration. This can…
The dynamics of stratified horizontal shear flows at low Péclet number
L. Cope, P. Garaud, C. P. Caulfield
We consider the dynamics of a vertically stratified, horizontally-forced Kolmogorov flow. Motivated by astrophysical systems where the Prandtl number is often asymptotically small,…
Weakly non-Boussinesq convection in a gaseous spherical shell
Lydia Korre, Nicholas Brummell, Pascale Garaud
We examine the dynamics associated with weakly compressible convection in a spherical shell by running 3D direct numerical simulations using the Boussinesq formalism [1]. Motivated…
