Abstract

871374 The linear stability of general two-phase flow models-II The technique for the linear stability analysis of two- phase flow models developed in a previous paper has been extended to deal with models containing space and time derivatives of the flow variables of arbitrary order. A number of current models for the description of stratified flow have been analysed in detail as an illustration of the utility of the technique. The role of interphase drag functions for long wavelengths and of surface tension for short wavelengths clearly emerges from these examples. Effects such as transverse momentum and viscosity are also contained in the examples considered. For long wavelengths some general results are given.
