Graduate level two phase flow boiling textbook

Click For Summary

Discussion Overview

The discussion revolves around the search for a graduate-level textbook that adequately covers the characteristics of two-phase flow during flow boiling. Participants explore the depth of coverage in forced convection courses and the complexities involved in two-phase heat transfer problems, particularly in the context of subcooled water undergoing flow boiling.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants suggest that a graduate-level forced convection course may provide only a brief introduction to two-phase flow, indicating that more in-depth study is necessary.
  • There is acknowledgment that two-phase heat transfer problems are significantly more complex than one-phase problems, involving intricate flow patterns and heat transfer mechanisms.
  • A participant mentions their specific research focus on the two-phase flow of subcooled water during flow boiling with non-uniform heat flux, seeking to understand the heat transfer mechanism from heating to dry-out.
  • Some participants propose that reviewing journal articles may be essential for obtaining usable formulas related to heat transfer in two-phase flow scenarios.
  • References to extensive literature and practical applications in industrial equipment are made, suggesting that practical design considerations may enhance understanding of two-phase heat transfer.
  • One participant recommends the textbook "Transport Phenomena" by Bird, Stewart, and Lightfoot for potential insights into boiling heat transfer.
  • Links to external resources on boiling heat transfer are shared, along with advice to combine theories of boiling and convective heat transfer for a comprehensive understanding.
  • A specific book, "Thermo-Hydraulics of Nuclear Reactors" by Brennen, is mentioned as a resource that includes chapters on two-phase water flow, particularly relevant to boiling water reactors.

Areas of Agreement / Disagreement

Participants express varying opinions on the adequacy of graduate-level resources for two-phase flow topics, with no consensus on a single textbook or approach. The complexity of two-phase heat transfer remains a point of contention, with multiple perspectives on how best to study the subject.

Contextual Notes

Participants note the challenges in solving mixed-mode heat transfer problems, which may require numerical solutions and specialized software. There is also mention of the need for specific assumptions and definitions when discussing two-phase flow phenomena.

I am looking for a graduate level textbook that would sufficiently describe the two phase flow characteristics during flow boiling. What textbook could I use to explore this topic?

Is a graduate level forced convection going to cover two phase flow?

You might get a brief introduction to the subject but very little more than that .

Two phase heat transfer problems are very much more difficult to work on than one phase problems . Apart from the actual heat transfer problem in vicinity of the heat transfer surfaces there are usually complex and energetic flow patterns in the bulk fluids to deal with .

Do you have a specific problem that you want to look at ?

My masters study is investigating the two phase flow of subcooled water undergoing flow boiling which is being heated by a non-uniform heat flux. I just want to get an understanding if the heat transfer mechanism from the initial heating up to the dry out portion.

Would looking at other journal articles be the only real course of action that would lead to usable formulas describing the heat transfer?
 
You asked specifically about undergraduate work . More generally there is extensive literature on this subject . I'm sure that @Chestermiller will be able to tell you where to find some of the better material .

Two phase heat transfer is actually to be found commonly in many types of industrial equipment and there has been extensive theoretical research and practical development of methods to do the calculations necessary and to come up with practical equipment designs .

You may be able to gain a lot of understanding of this subject by looking at actual equipment designs and at published work which deals with the design of equipment and necessary calculations in a more practical rather than purely theoretical manner .

I wish I could help with this, but I have little experience with two phase flow problems like that described by the OP. I would start by looking in Transport Phenomena by Bird, Stewart, and Lightfoot, and seeing whether they have anything specific on boiling heat transfer (and the resulting flow), or if they cite any references.

A general search on 'boiling heat transfer' produces a large number of hits .

Put the theory of boiling heat transfer together with ordinary convective heat transfer theory for the non boiling zones of you heat transfer surfaces and I think that you will get most of what you need to get started .

Problems for this kind of mixed mode heat transfer can get very complicated and final solutions often have to be obtained numerically . There is some specialised software available .

Search for books on "thermal hydraulics" or ""thermo-hydraulics."

Thermo-Hydraulics of Nuclear Reactors by Brennen ends with two chapters on two-phase water flow, for example. The last chapter is very specific to flow in boiling water reactors, but it does help provide context and examples for the previous chapter's material.
