Transition from classical to ultimate melting
Edoardo Bellincioni, Kevin Zhong, Christopher J. Howland +4
Melting is omnipresent in nature and technology, with applications ranging from metallurgy, biology, food science, and latent thermal energy storage to oceanography, geophysics, an…
Bistability in radiatively heated melt ponds
Rui Yang, Christopher J. Howland, Hao-Ran Liu +2
Melting and solidification processes, intertwined with convective flows, play a fundamental role in geophysical contexts. One of these processes is the formation of melt ponds on g…
A front-tracking immersed-boundary framework for simulating Lagrangian melting problems
Kevin Zhong, Christopher J. Howland, Detlef Lohse +1
In so-called Lagrangian melting problems, a solid immersed in a fluid medium is free to rotate and translate in tandem with its phase-change from solid to liquid. Such configuratio…
Turbulent mixed convection in vertical and horizontal channels
Christopher J. Howland, Guru Sreevanshu Yerragolam, Roberto Verzicco +1
Turbulent shear flows driven by a combination of a pressure gradient and buoyancy forcing are investigated using direct numerical simulations. Specifically, we consider the setup o…
Scaling relations for heat and momentum transport in sheared Rayleigh-Bénard convection
Guru Sreevanshu Yerragolam, Christopher J. Howland, Richard J. A. M. Stevens +3
We provide scaling relations for the Nusselt number and the friction coefficient in sheared Rayleigh-Bénard convection, i.e., in Rayleigh-Bénard flow with Couette or P…
Towards the understanding of convective dissolution in confined porous media: thin bead pack experiments, two-dimensional direct numerical simulations and physical models
Marco De Paoli, Christopher J. Howland, Roberto Verzicco +1
We consider the process of convective dissolution in homogeneous and isotropic porous media. The flow is unstable due to the presence of a solute that induces a density difference…
Shape effect on ice melting in flowing water
Rui Yang, Christopher J. Howland, Hao-Ran Liu +2
Iceberg melting is a critical factor for climate change, contributing to rising sea levels and climate change. However, the shape of an iceberg is an often neglected aspect of its…
Ice melting in salty water: layering and non-monotonic dependence on the mean salinity
Rui Yang, Christopher J. Howland, Hao-Ran Liu +2
The presence of salt in ocean water strongly affects the melt rate and the shape evolution of ice, both of utmost relevance in geophysical and ocean flow and thus for the climate.…
Double-diffusive transport in multicomponent vertical convection
Christopher J. Howland, Roberto Verzicco, Detlef Lohse
Motivated by the ablation of vertical ice faces in salt water, we use three-dimensional direct numerical simulations to investigate the heat and salt fluxes in two-scalar vertical…
Boundary layers in turbulent vertical convection at high Prandtl number
Christopher J. Howland, Chong Shen Ng, Roberto Verzicco +1
Many environmental flows arise due to natural convection at a vertical surface, from flows in buildings to dissolving ice faces at marine-terminating glaciers. We use three-dimensi…
Quantifying mixing and available potential energy in vertically periodic simulations of stratified flows
Christopher J. Howland, John R. Taylor, C. P. Caulfield
Turbulent mixing exerts a significant influence on many physical processes in the ocean. In a stably stratified Boussinesq fluid, this irreversible mixing describes the conversion…
Shear-induced breaking of internal gravity waves
Christopher J. Howland, John R. Taylor, C. P. Caulfield
Motivated by observations of turbulence in the strongly stratified ocean thermocline, we use direct numerical simulations to investigate the interaction of a sinusoidal shear flow…
It's harder to splash on soft solids
Christopher J. Howland, Arnaud Antkowiak, J. Rafael Castrejón-Pita +4
Droplets splash when they impact dry, flat substrates above a critical velocity that depends on parameters such as droplet size, viscosity and air pressure. By imaging ethanol drop…
