What is Faraday instability?

2014 APS/DFD Milton van Dyke Award Winner In 1831, Michael Faraday discovered that a liquid undergoing vertical vibration is unstable to surface waves. We show the Faraday instability in floating liquid drops, as an example of hydrodynamic instability that develops in a domain with flexible boundaries. read more

Faraday instability is a result of the parametric resonance of interfacial wave modes with an imposed vibrational frequency. In simple words, A vessel containing a heavy liquid vibrates vertically with constant frequency and amplitude. read more

When the vibration frequency exceeds a critical value, the flat hydrostatic surface becomes unstable. This is known as the Faraday instability. Faraday first described them in an appendix to an article in the Philosophical Transactions of the Royal Society of London in 1831. read more

Observations of the Faraday Instability John Bollenbacher, Catherine Chambers, Tara Cunningham, and Preston Putzel December 10th, 2014 1 Motivations First observed by Michael Faraday in 1831 [1], Faraday waves are surface instabilities that arise in a uid undergoing vertical oscillations above a critical amplitude and/or frequency. read more
