1. Pattern Formation and Chaos in Taylor-Couette flow
Taylor-Couette flow
Front view
Re ~72.0
The flow between concentric cylinders produces some interesting steady patterns, oscillations and chaos as the cylinders are rotated faster.
2. Elastic Instabilities in Cellular Solids
An interesting new pattern develops when a square array of holes in an elastic solid is compressed in one direction.
3. Cavitation in Viscous and non-Newtonian Fluids
Bubbles formed in the fluid layer between a steel ball and a moving wall.
4. Transition to Turbulence in a Pipe
A turbulent puff in pipe flow.
5. Flow Through a Sudden Expansion
An MRI image of the oscillations in an expanding pipe flow.
6. Patterned Granular Segregation
A mixture segregates into an interesting pattern when shaken from side-to-side.
7. The Stress Dip Under a Sandpile
The stress pattern under a 'sandpile' is visualized using photoelastic discs.
8. Buckling of An Elastic Ring
A floating circular elastic ring buckles as the water drains through a glass funnel.
