Following these results, it is presumed that the classical Rayleigh theorem is wrong which states that a necessary condition for inviscid flow instability is the existence of an inflection point on the velocity profile. In present study, we show rigorously the proof why Rayleigh theorem is wrong. WebFeb 2, 2011 · Rayleigh’s analysis takes into account surface tension and inertial forces but neglected viscosity and the effect of the surrounding air. Weber (1931) later extended Rayleigh’s work to include the effect of air resistance on the disintegration of jets into drops. He found that air friction shortens the optimum wavelength for drop formation.
