Bifurcations in Stokes Flow Sedimentation
Elias Huseby, Pierre Mathier, Meera Das +5
Particles whose shapes couple translation to rotation display a rich array of behaviors as they sediment at low Reynolds number. We introduce a unifying perspective in which the po…
Avalanches of choice: how stranger-to-stranger interactions shape crowd dynamics
Ziqi Wang, Alessandro Gabbana, Federico Toschi
Pedestrian routing choices play a crucial role in shaping collective crowd dynamics, yet the influence of interactions among unfamiliar individuals remains poorly understood. In th…
Inertial rotation of a small oblate spheroid in a simple shear flow
Ziqi Wang, Xander M. de Wit, Davide Di Giusto +5
We compare experiments and fully-resolved particle simulations designed to match the experimental conditions of a weakly inertial, neutrally buoyant, moderately oblate spheroid in…
Flow-driven hysteresis in the transition boiling regime
Alessandro Gabbana, Xander M. de Wit, Linlin Fei +3
Transition boiling is an intermediate regime occurring between nucleate boiling, where bubbles at the surface efficiently carry heat away, and film boiling, where a layer of vapor…
Intermittency suppression in turbulence via forced light particles
André Freitas, Xander M. de Wit, Ziqi Wang +2
We investigate how turbulence is reshaped by the presence of externally forced light particles, using high-resolution direct numerical simulations with four-way coupling. The parti…
Tracking the rotation of light magnetic particles in turbulence
Chunlai Wu, Rudie P. J. Kunnen, Ziqi Wang +3
Particle-laden turbulence involves complex interactions between the dispersed and continuous phases. Given that particles can exhibit a wide range of properties, such as varying de…
Stochastic resonance of rotating particles in turbulence
Ziqi Wang, Xander M. de Wit, Roberto Benzi +4
The chaotic dynamics of small-scale vorticity plays a key role in understanding and controlling turbulence, with direct implications for energy transfer, mixing, and coherent struc…
Localization-delocalization transition for light particles in turbulence
Ziqi Wang, Xander M de Wit, Federico Toschi
Small bubbles in fluids raise to the surface due to Archimede's force. Remarkably, in turbulent flows this process is severely hindered by the presence of vortex filaments, which a…
Sea Water Freezing Modes in a Natural Convection System
Yihong Du, Ziqi Wang, Linfeng Jiang +2
Sea ice is crucial in many natural processes and human activities. Understanding the dynamical couplings between the inception, growth and equilibrium of sea ice and the rich fluid…
Equilibrium states of the ice-water front in a differentially heated rectangular cell
Ziqi Wang, Enrico Calzavarini, Chao Sun
We study the conductive and convective states of phase-change of pure water in a rectangular container where two opposite walls are kept respectively at temperatures below and abov…
Ice front shaping by upward convective current
Ziqi Wang, Linfeng Jiang, Yihong Du +2
The extent and the morphology of ice forming in a differentially heated cavity filled with water is studied by means of experiments and numerical simulations. We show that the main…
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…
