Global and local statistics in turbulent emulsions

Lei Yi, Federico Toschi, Chao Sun

Turbulent emulsions are complex physical systems characterized by a strong and dynamical coupling between small-scale droplets and large-scale rheology. By using a specifically des…

A Lattice Boltzmann Method for Relativistic Rarefied Flows in (2 + 1) Dimensions

Lorenzo Bazzanini, Alessandro Gabbana, Daniele Simeoni +2

We propose an extension to recently developed Relativistic Lattice Boltzmann solvers (RLBM), which allows the simulation of flows close to the free streaming limit. Following previ…

Wall-induced anisotropy effects on turbulent mixing in channel flow: A network-based analysis

Davide Perrone, J. G. M. Kuerten, Luca Ridolfi +1

Turbulent mixing is studied in the Lagrangian framework with an approach based on the complex network formalism. We consider the motion of passive, noninertial particles inside a t…

Evaporation-Induced Crystallization of Surfactants in Sessile Multicomponent Droplets

Yaxing Li, Valentin Salvator, Herman Wijshoff +2

Surfactants have been widely studied and used in controlling droplet evaporation. In this work, we observe and study the crystallization of sodium dodecyl sulfate (SDS) within an e…

How the growth of ice depends on the fluid dynamics underneath

Ziqi Wang, Enrico Calzavarini, Chao Sun +1

Convective flows coupled with solidification or melting in water bodies play a major role in shaping geophysical landscapes. Particularly in relation to the global climate warming…

A nonlinear model of vortex-induced forces on an oscillating cylinder in a fluid flow

Jan Decuyper, Tim De Troyer, Koen Tiels +2

A nonlinear model relating the imposed motion of a circular cylinder, submerged in a fluid flow, to the transverse force coefficient is presented. The nonlinear fluid system, featu…

Rayleigh-Taylor instability by segregation in an evaporating multi-component microdroplet

Yaxing Li, Christian Diddens, Tim Segers +3

The evaporation of multi-component droplets is relevant to various applications but challenging to study due to the complex physicochemical dynamics. Recently, Li (2018) reported e…

Controlling Rayleigh-Bénard convection via Reinforcement Learning

Gerben Beintema, Alessandro Corbetta, Luca Biferale +1

Thermal convection is ubiquitous in nature as well as in many industrial applications. The identification of effective control strategies to, e.g., suppress or enhance the convecti…

Frictional boundary layer effect on vortex condensation in rotating turbulent convection

Andrés J. Aguirre Guzmán, Matteo Madonia, Jonathan S. Cheng +3

We perform direct numerical simulations of rotating Rayleigh--Bénard convection of fluids with low () and high () Prandtl numbers in a horizontally periodic layer wit…
