Because of the practical importance of two-phase flow instabilities, substantial efforts have been made to date to understand the physical phenomena governing such instabilities and to develop computational tools to model the dynamics of marginally-stable/unstable boiling systems. The purpose of this paper is to present an overview of the recent progress in the area of modeling two-phase flow dynamics and in the development of new methods for the analysis of flow-induced instabilities.
Two major issues will be discussed. First, an integrated methodology for the analysis of flow-induced instabilities in boiling channels and systems using a multifield model will be presented. Secondly, a new concept of multidimensional stability analysis will be introduced.
