WebSummary. This course covers the theoretical and practical analysis of two-phase flow and applications. Fundamental two-phase heat transfer in the form of condensation and boiling are studied in detail. Advanced topics such as microchannel two-phase flow, microfinned tubes and oil effects are also handled. WebTwo phase flow boiling heat transfer is attractive over single phase because of high heat transfer coefficient and high heat removal capability for a given mass flow rate. In this Paper, The study presents the fundamentals of flow boiling heat.
