A reduced model for salt-finger convection in the small diffusivity ratio limit
Jin-Han Xie, Benjamin Miquel, Keith Julien +1
A simple model of nonlinear salt-finger convection in two dimensions is derived and studied. The model is valid in the limit of small solute to heat diffusivity ratio and large den…
Inertia-less convectively-driven dynamo models in the limit of low Rossby number and large Prandtl number
Michael A. Calkins, Keith Julien, Steven M. Tobias
Compositional convection is thought to be an important energy source for magnetic field generation within planetary interiors. The Prandtl number, , characterizing compositiona…
The effects of Ekman pumping on quasi-geostrophic Rayleigh-Benard convection
Meredith Plumley, Keith Julien, Philippe Marti +1
Numerical simulations of 3D, rapidly rotating Rayleigh-Benard convection are performed using an asymptotic quasi-geostrophic model that incorporates the effects of no-slip boundari…
Convection-driven kinematic dynamos at low Rossby and magnetic Prandtl numbers
Michael A. Calkins, Louie Long, David Nieves +2
Most large-scale planetary magnetic fields are thought to be driven by low Rossby number convection of a low magnetic Prandtl number fluid. Here kinematic dynamo action is investig…
Investigations of non-hydrostatic, stably stratified and rapidly rotating flows
David Nieves, Ian Grooms, Keith Juilen +1
We present an investigation of rapidly rotating (small Rossby number ) and stratified turbulence where the stratification strength is varied from weak (large Froude number…
A nonlinear model for rotationally constrained convection with Ekman pumping
Keith Julien, Jonathan M. Aurnou, Michael A. Calkins +4
It is a well established result of linear theory that the influence of differing mechanical boundary conditions, i.e., stress-free or no-slip, on the primary instability in rotatin…
