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…
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…
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…
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…
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…
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…
