Rayleigh disk experiment
WebTorque on Rayleigh disk in a resonating tube, for high pitch sounds.---In the case of a disk 15 cm in diam. in a tube 16 cm in diam., a study of the deflection as a function of wave-length, 4 to 28 cm, showed that for a wave-length of 28 cm the disk tended to set itself parallel to the axis of the resonator, and hence was deflected in a direction opposite to the usual one. …

At nanometer scales, thermal fluctuations are comparable to surface energy densities. Consequently, at these scales, thermal fluctuations play a significant role in the dynamics of the instability. These microscopic …
Web(Rayleigh, 1878) As with Rayleigh, the entirely intellectual exercise of studying this problem is likely fulfilling. The system represents one of many examples of dynamic surface tension fluid flows. The relatively simple experimental results give rise to a rigorous mathematical representation that robustly explains the underlying phenomena.
