The prey-predator motion of the active droplets
Yibo Chen, Kai Leong Chong, Roberto Verziccoa +1
We present a generic solution for the relative motion of two diffusiophoretic prey-predator particles of arbitrary chemical activity Ai and radius Ri, where i = 1;2 refers to the p…
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…
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…
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…
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…
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…
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…
Circular objects do not melt the slowest in water
Rui Yang, Thijs van den Ham, Roberto Verzicco +2
We report on the melting dynamics of ice suspended in fresh water and subject to natural convective flows. Using direct numerical simulations we investigate the melt rate of ellips…
Mass transport at gas-evolving electrodes
Farzan Sepahi, Roberto Verzicco, Detlef Lohse +1
Direct numerical simulations are utilised to investigate mass transfer processes at gas-evolving electrodes that experience successive formation and detachment of bubbles. The gas-…
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…
Turbulent Taylor-Couette flow with stationary inner cylinder
Rodolfo Ostilla-Mónico, Roberto Verzicco, Detlef Lohse
A series of direct numerical simulations of Taylor-Couette (TC) flow, the flow between two coaxial cylinders, with the outer cylinder rotating and the inner one fixed, were perform…
The effect of velocity boundary conditions on the heat transfer and flow topology in two-dimensional Rayleigh-Bénard convection
Erwin P. van der Poel, Rodolfo Ostilla Mónico, Roberto Verzicco +1
The effect of various velocity boundary condition is studied in two-dimensional Rayleigh-Bénard convection. Combinations of no-slip, stress-free and periodic boundary conditions ar…
