Gas bubble dynamics
Dominique Legendre, Roberto Zenit
The study of gas bubble dynamics in liquids is justified by the numerous applications and natural phenomena where this two-phase flow is encountered. Gas bubbles move as forces are…
Asymmetry of motion: vortex rings crossing a density gradient
Yunxing Su, Monica M. Wilhelmus, Roberto Zenit
Vortex rings are critical for thrust production underwater. In the ocean, self-propelled mesozooplankton generate vortices while swimming within a weakly stratified fluid. While la…
The presence of surfactants controls the stability of bubble chains in carbonated drinks
Omer Atasi, Mithun Ravisankar, Dominique Legendre +1
Bubbles appear when a carbonated drink is poured in a glass. Very stable bubble chains are clearly observed in champagne, showing an almost straight line from microscopic nucleatio…
Viscoelastic levitation
Yunxing Su, Alfonso Castillo, On Shun Pak +2
The effects of viscoelasticity have been shown to manifest themselves via symmetry breaking. In this investigation, we show a novel phenomenon that arises from this idea. We observ…
Hydrodynamic interaction of a bubble pair in viscoelastic shear-thinning fluids
Mithun Ravisankar, Alam Garciduenas Correa, Yunxing Su +1
We experimentally investigate the interaction between a pair of bubbles ascending in a stagnant viscoelastic shear-thinning fluid. In particular, we focus on the effect of bubble s…
Force and torque-free helical tail robot to study low Reynolds number microorganism swimming
Asimanshu Das, Matthew Styslinger, Daniel M. Harris +1
Helical propulsion is used by many microorganisms to swim in viscous-dominated environments. Their swimming dynamics are relatively well understood, but detailed study of the flow…
