Understanding Two-Phase Flows — Lesson 5

This lesson covers the analysis of two-phase flows, focusing on the nomenclature and terminologies used in this field. It explains the importance of understanding the specific definitions and parameters used in two-phase flow analysis, such as mass flow rate, interfacial property, nomenclature, and velocity. The lesson also discusses the concept of in-situ volume fraction, inlet volume fraction, and quality in two-phase flows. It further elaborates on the measurement of these parameters and their significance in practical applications. For instance, the lesson explains how to measure the in-situ composition of two-phase flows and how it differs from the inlet volume fraction.
