Summary
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.Content
1. Introduction to two-phase flow patterns (annular, mist, bubbly,
stratified, etc).
2. Two-phase flow pattern maps and transition theory.
3. Homogeneous and heterogeneous flow models.
4. Film condensation (Nusselt equation, multitube models,
condensation on enhanced fin geometries).
5. Convective condensation (flow pattern effects, various models and
methods for plain and internally enhanced channels).
6. Fundamentals of pool boiling (nucleation, bubble dynamics,
nucleate boiling, peak heat flux models, film boiling).
7. Convective boiling (heat transfer models and design methods for
evaporation inside tubes and outside tube bundles).
8. Combined heat and mass transfer in phase change processes
(condensation in presence of non-condensable gas and evaporation of mixtures.
Keywords
Two-phase heat transfer, two-phase flow, condensation, convection, evaporation
Learning Prerequisites
Recommended courses
- Heat and mass transfer (ME-341)
Important concepts to start the course
Basic understanding of:
- the physics of heat conduction and fluid flow
- thermodynamics of pure fluids
- mass, momentum, and energy conservation on both differential and finite control volume basis
Familiarity with engineering conventions for representing heat transfer, particularly in pipes, such as heat transfer coefficient, friction factor, Reynolds number, Nusselt number, etc.
Basic skills in MATLAB or a computer langauge of your choice.
Learning Outcomes
By the end of the course, the student must be able to:- Explain and apply the concepts of heat and mass transfer, E3
