Abstract

An overview of stability of separated flows is presented. Separated flow is a flow in which gas and liquid are continuous along the pipe, namely, it includes the stratified and the annular flow patterns. The stability of separated flow is discussed using several approaches: The Viscous and the Inviscid Kelvin-Helmholtz stability analyzes and the Structural stability analysis. The various approaches and the physical interpretation of the different analyses are presented. It is shown that one should consider the two types of KH stability analyses as well as the structural analysis in order to obtain a complete picture regarding the stability of separated flow. Special attention is given to the role of viscosity on the stability, the possibility of having multiple steady state solutions and the application to flow pattern prediction.
