Elastic pseudoturbulence induced by low-Galilei settling spheres
Ludovico Fossà, Michele Macaluso, Luca Brandt +1
In this Letter, we show how a suspension of light solid spheres settling through a polymer solution results in a chaotic and highly-intermittent state. By leveraging particle-resol…

Marangoni modulation of coupled Rayleigh-Taylor and Faraday instabilities in vertically oscillated liquid films
Jun Gao, Senlin Zhu, Luca Brandt +3
We investigate the Marangoni modulation of coupled Rayleigh-Taylor and Faraday instabilities in a vertically oscillated Newtonian liquid film carrying insoluble surfactants. Linear…

Elastoviscoplastic fluid flow past a circular cylinder
S. Parvar, K. T. Iqbal, M. N. Ardekani +2
The combined effect of fluid elasticity and yield-stress on the flow past a circular cylinder is studied by two-dimensional direct numerical simulation. We analyze the effects of y…
