A note on the relation between temporally-increasing and spatially-increasing disturbances in hydrodynamic stability
TL;DR: In this paper, the frequency and amplification rates for a disturbance growing with respect to time are compared with those of a spatially growing wave having the same wave number, and it is shown that the frequencies are equal to a high order of approximation.

N. Dombrowski,W.R. Johns +1 more
TL;DR: In this paper, an analysis of the aerodynamic instability and disintegration of viscous sheets with particular reference to those produced by fan-spray nozzles is made, and a drop-size relation is formulated which compares favourably with experimental data in the literature.

Investigation of the instability of a moving liquid film
TL;DR: In this paper, the stability of a thin layer of liquid moving in still air is studied theoretically with the object of throwing light on the break-up of films during atomization, and it is found that instability occurs if W = T/ρ 1U2h < 1 and that the wavelength for maximum growth factor, for W « 1, is λ = (4πT/ρ 2U2U2).
