Magneto-Stokes Flow in a Shallow Free-Surface Annulus
Cy S. David, Eric W. Hester, Yufan Xu +1
In this study, we analyse "magneto-Stokes" flow, a fundamental magnetohydrodynamic (MHD) flow that shares the cylindrical-annular geometry of the Taylor-Couette cell, but uses appl…
Fluid dynamics alters liquid-liquid phase separation in confined aqueous two-phase systems
Eric W. Hester, Sean P. Carney, Vishwesh Shah +4
Liquid-liquid phase separation is key to understanding aqueous two-phase systems (ATPS) arising throughout cell biology, medical science, and the pharmaceutical industry. Controlli…
Orthogonal signed-distance coordinates and vector calculus near evolving curves and surfaces
Eric W. Hester, Geoffrey M. Vasil
We provide an elementary derivation of an orthogonal coordinate system for boundary layers around evolving smooth surfaces and curves based on the signed-distance function. We go b…
Moosinesq Convection in the Cores of Moosive Stars
Evan H. Anders, Evan B. Bauer, Adam S. Jermyn +7
Stars with masses have core convection zones during their time on the main sequence. In these moosive stars, convection…
On the stability of isothermal shocks in black hole accretion disks
Eric W. Hester, Geoffrey M. Vasil, Martin Wechselberger
Most black holes possess accretion disks. Models of such disks inform observations and constrain the properties of the black holes and their surrounding medium. Here, we study isot…
Aspect ratio affects iceberg melting
Eric W. Hester, Craig D. McConnochie, Claudia Cenedese +2
Iceberg meltwater is a critical freshwater flux from the cryosphere to the oceans. Global climate simulations therefore require simple and accurate parameterisations of iceberg mel…
Improved phase-field models of melting and dissolution in multi-component flows
Eric W. Hester, Louis-Alexandre Couston, Benjamin Favier +2
We develop and analyse the first second-order phase-field model to combine melting and dissolution in multi-component flows. This provides a simple and accurate way to simulate cha…
Topography generation by melting and freezing in a turbulent shear flow
Louis-Alexandre Couston, Eric Hester, Benjamin Favier +3
We report an idealized numerical study of a melting and freezing solid adjacent to a turbulent, buoyancy-affected shear flow, in order to improve our understanding of topography ge…
Bistability in Rayleigh-Bénard convection with a melting boundary
Jhaswantsing Purseed, Benjamin Favier, Laurent Duchemin +1
A pure and incompressible material is confined between two plates such that it is heated from below and cooled from above. When its melting temperature is comprised between these t…
Improving convergence of volume penalised fluid-solid interactions
Eric W. Hester, Geoffrey M. Vasil, Keaton J. Burns
We analyse and improve the volume-penalty method, a simple and versatile way to model objects in fluid flows. The volume-penalty method is a kind of fictitious-domain method that a…
