Sinopsis

Developing reliable models for mechanics and heat transfer in two phase flow is difficult because of the existence of a variety of flow patterns. Each of the patterns requires a different approach to modelling because in each the controlling physical processes differ. Approaches to physically based modelling for horizontal tube systems are presented in this lecture. Models for predicting flow patterns are discussed for steady adiabatic flow without phase change as well as for transient flow and flow with boiling and condensation. Based on this prediction scheme, it is possible to consider the details for modelling the flow and heat transfer for each pattern. An an example, the present status of modelling the flow mechanics and heat transfer for intermittent (slug) flow is discussed.
