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…
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…
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…
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…
