概要
- 論文の詳細を見る
Viscous potential flow (VPF) analysis is made of Kelvin-Helmholtz instability of a liquid sheet in between gases. Its dispersion relation for temporal instability is the quartic equation in a complex growth rate (or angular frequency). If the two gases are the same, the quartic is separated into two quadratic ones for an antisymmetric mode and a symmetric mode of the interfacial patterns. This VPF bridges inviscid potential flows with fully viscous flows. The dispersion relation for spatial instability is given as a transcendental function of wavenumber. The transition between the absolute and convective instabilities is well predicted.
