WebHistory. The Plateau–Rayleigh instability is named for Joseph Plateau and Lord Rayleigh.In 1873, Plateau found experimentally that a vertically falling stream of water will break up into drops if its length is greater than about 3.13 to 3.18 times its diameter, which he noted is close to π. Later, Rayleigh showed theoretically that a vertically falling column of non … WebFeb 26, 2013 · CFX Cavitation Model. i have a couple of questions regarding the CFX Cavitation Model.
