Autonomous route to the strange attractor: the many life stages of the chaotic bubblewheel
Michael Zhao, Saverio E. Spagnolie
A body floating atop a supersaturated fluid may accumulate bubbles along its underbelly, which can render the body rotationally unstable. But rotation can strip the surface of thes…
Levitation and dynamics of bodies in supersaturated fluids
Saverio E. Spagnolie, Samuel Christianson, Carsen Grote
A body immersed in a supersaturated fluid like carbonated water can accumulate a dynamic field of bubbles upon its surface. If the body is mobile, the attached bubbles can lift it…
Swimming in Complex Fluids
Saverio E. Spagnolie, Patrick T. Underhill
We review the literature on swimming in complex fluids. A classification is proposed by comparing the length and time scales of a swimmer with those of nearby obstacles, interprete…
Velocity fluctuations in a dilute suspension of viscous vortex rings
Thomas Morrell, Saverio Spagnolie, Jean-Luc Thiffeault
We explore the velocity fluctuations in a fluid due to a dilute suspension of randomly-distributed vortex rings at moderate Reynolds number, for instance those generated by a large…
A generalized traction integral equation for Stokes flow, with applications to near-wall particle mobility and viscous erosion
William H. Mitchell, Saverio E. Spagnolie
A double-layer integral equation for the surface tractions on a body moving in a viscous fluid is derived which allows for the incorporation of a background flow and/or the presenc…
Geometric capture and escape of a microswimmer colliding with an obstacle
Saverio E. Spagnolie, Gregorio R. Moreno-Flores, Denis Bartolo +1
Motivated by recent experiments, we consider the hydrodynamic capture of a microswimmer near a stationary spherical obstacle. Simulations of model equations show that a swimmer app…
