Controlling the Saffman-Taylor instability
1,838 views
This video shows finite element simulations of the air-fluid interface in a lifting Hele-Shaw cell. These demonstrate the existence of several different self-similar modes of...

Controlling vortex breakdown in swirling pipe flow
3,735 views
A vortex breakdown occurs as fluid flows from a rotating pipe into a stationary pipe at a constant rate. The decaying swirl creates an adverse pressure gradient on the pipe axis,...

Droplet breakage
1,972 views
As a liquid bath is perturbed, at a particular acceleration standing waves, called Faraday waves, will appear on the whole surface of the bath. As acceleration increases beyond...

Dye flow visualisation of vortex shedding in a synthetic jet
3 views
Dye visualisation of a synthetic jet in cross flow in water, whose non-dimensional stroke length exceeds the circulation limit of the primary vortex. Consequently, excess...

Instabilities in ferrofluid
1,923 views
A 50 mm long magnet placed at the bottom of a petri dish with 1 mm layer of ferrofluid. Following the gradient of magnetic field, the fluid forms a hump over the magnet. First,...

Marangoni instability from picolitre sessile droplets
2,009 views
What if a picolitre ethanol drop hits a thin water film of a few microns? High speed camera caught the moment of drop impact: water film is contracted into a drop and repelled,...

Radial Marangoni instability in an evaporating sessile droplet
1,992 views
Evaporation of a picolitre droplet of ethanol and water with suspended particles that track Marangoni driven flows. A radial instability in the flow leads to the appearance of a...
