Transition to the ultimate regime of turbulent convection in stratified inclined duct flow
Rundong Zhou, Adrien Lefauve, Roberto Verzicco +1
The stratified inclined duct (SID) flow provides a canonical model for sustained, buoyancy-driven exchange between two reservoirs of different density, and emerges as a new paradig…
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…
Solute mixing in porous media with dispersion and buoyancy
Marco De Paoli, Guru Sreevanshu Yerragolam, Roberto Verzicco +1
We analyse the process of convective mixing in two-dimensional, homogeneous and isotropic porous media with dispersion. We considered a Rayleigh-Taylor instability in which the pre…
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…
Particle chirality does not matter in the large-scale features of strong turbulence
Giulia Piumini, Martin P. A. Assen, Detlef Lohse +1
We use three-dimensional direct numerical simulations of homogeneous isotropic turbulence in a cubic domain to investigate the dynamics of heavy, chiral, finite-size inertial parti…
