FSH3801 Two-Phase Flow and Heat Transfer 6.0 credits

Multiphase flow and heat transfer is an area of interests in fluid dynamics and heat transfer where several different phases co-exist. Although these transport phenomena can be seen our every day-life, for instance, from water boiling in a kitchen and blood streaming in a body to the operation of huge power plants, surprisingly we have little knowledge of multiphase flow since the physical understanding of the phenomena is extremely challenging. It is even more surprise that the limited knowledge we have got completely changed our life and allowed us to be distinguished from our predecessors. We have been realizing now that new knowledge is an essence of understanding nature itself.

This course, “Two-phase Flow and Heat Transfer,” aims to provide a rudimentary exposure to the thermo-fluid transport phenomena in one of the simplest multiphase systems: two-phase. This course also aims to guide learners to formulate and solve problems associated with two-phase flow phenomena. The course is designed to encourage the learners to develop their heuristic learning process based on the first principles of the modern physics, which involves theory learning and technical problem solving as well as working on a task/project and reporting the results.

This course basically deals with four parts of the subject;

(a) concept of two-phase phenomena,

(b) two-phase fluid mechanics,

(c) two-phase heat transfer and

(d) special topics of two-phase transport phenomena.

The first part of the course starts with a short review of the history of two-phase flow and an introduction to two-phase parameters. Fundamental concepts of two-phase system and phase configurations, such as flow patterns, will also be introduced. The second part of the course stretches into two-phase flow modeling. The third part extends to the heat transfer models with phase changes including natural/forced convective boiling, critical heat flux (CHF), and condensation. Meanwhile, the course will introduce some important two-phase phenomena such as counter-current flow, critical flow, etc. During the course period, the students are requested to carry out a term project for their choices of interests that could demonstrate their understanding of the subject.

The students taking this course are assumed to have taken the elementary courses on the fluid mechanics, thermodynamics, and heat transfer. Basic understanding and hand-on experience of numerical programming will be a good help. The class instructions will be delivered in English.

Content and learning outcomes

Course contents

This course mainly deals with four parts of the subject:
(a) concept of two-phase phenomena,
(b) two-phase fluid mechanics,
(c) two-phase heat transfer and
(d) special topics of two-phase transport phenomena.

The first part starts with a review of two-phase research history and an introduction to two-phase parameters and terminology. Fundamental concepts of two-phase modeling and phase configurations, such as flow patterns, will also be introduced. The second part of the course stretches into two-phase flow modeling, The third part of the course extends to the heat transfer models with phase changes including natural/forced convective boiling, critical and post-critical heat transfer and condensation. In the meantime, the course will introduce some important two-phase phenomena such as counter-current flow, critical flow, etc. Students are requested to carry out a term-project within a topic of their interest that can demonstrate their understanding of the subject.

Intended learning outcomes

  1. Describe the most important phenomena and principles of two-phase flow in engineering applications.
  2. Explain the main points of boiling and condensation, heat transfer, and their enhancement methods.
  3. Describe the concept boiling crisis (e.g., DNB - departure from nucleate boiling, and dryout) and its modeling.
  4. Apply the basic two-phase models and flow pattern maps to calculate the pressure drops of two-phase flow at various conditions.
  5. Apply the models of critical flow and flooding to analyze limiting flow of engineering processes.
  6. Apply the learning outcomes to write a scientific review for a topic (to be Identified) in the field of two- phase flow and heat transfer.
