Description including Unit Aims

Multiphase flow is an inherently interesting branch of fluid mechanics. In single-phase fluid mechanics problems can be solved at quite a fundamental level with a few notable exceptions such as turbulence. Simply combining two or more phases generates interesting problems become much more difficult to solve because of the difficulty of describing a dispersed phase, the structures that can arise in a multiphase flow, and the interactions between the different phases. Interesting as these problems are, multiphase flows are everywhere, in any process where you want different materials to mix, so what are the methods that allow you to overcome the unique challenges of multiphase flows that will enable you to make stuff?

The unit will also cover more general skills. This course extends the techniques of fluid mechanics to areas where fundamental understanding is poor but practical outcomes are important. To be able to do this takes a combination of the ability to analyse a system, to be able to draw on a variety of technical resources, technical skill, engineering nous.

The aims of the unit are therefore:

1. Equip you with the skills necessary to describe, understand, and calculate multiphase flows.
2. To address aspects of the full range of multiphase flows.
3. To be able to find and use methods that allow you to successfully tackle diverse and complex problems.

Intended Learning Outcomes

1. To be able to characterise and analyse multiphase flows
2. To be able to analyse and solve multiphase flow engineering problems.
3. To be able to apply a variety of approaches to solving practical multiphase problems.
4. To be able to synthesise different approaches and information from a wide range of sources in order to suggest a solution to multiphase problems.
5. To be able to evaluate the application of multiphase flow methods to a practical problem and justify the approaches used.

Programme learning objectives covered: A8, B1, B4, B5, B6, B7, B8, C1, C3, C4, C6, C8, C9, C10, C11

Teaching Information

The unit will consist of eleven two-hours sessions, one a week in TB2. These will consist partly of lectures and partly of exercises. As well as straight technical content, there will be some instruction on finding, reading, and combining technical literature.

Feedback will be through in-class exercises, problem sheets, and voluntary, marked formative exercises, and at least two coaching sessions for the summative assessment.

Assessment Information

Summative assessment is through a coursework assignment where students will be invited to answer specific but open-ended questions about a given multiphase flow. Some references will be provided, but students will be expected to read more widely and successfully synthesise information to achieve the highest marks. Maximum length of the report will be 10 pages.

During the unit there will be exercises in class and problem sheets available for the fundamentals half of the unit. There will be some exercises available in the second half, but also a coaching session for the writing of the summative exercise.

Reading and References

There is a comprehensive reading list set-up that can be accessed from the university's website or via Blackboard. Extensive references to papers are given and used in the teaching, but details of these and how they should be tackled will be given in the course. However, there is a comprehensive textbook that is followed during the teaching.
