This course aims to equip students with the skills and the knowledge necessary to solve problems in thermodynamics and fluid mechanics. In fluid mechanics, the framework of the subject is set out to provide a secure base from which several fundamental fluid flows and concepts can be explored. The general approach is to enable students to develop further skills in the future. For thermodynamics the unit will provide students with knowledge and understanding of the operation and analysis of basic thermodynamic machines and systems, such as turbines, refrigerators, steam cycles, air conditioning and combustion, based upon a thorough knowledge of the first and second laws of thermodynamics. It also provides an appreciation of the importance of the basic modes of heat transfer and the ability to analyse simple heat transfer problems (including simple heat-exchanger design) in an engineering context.

Aims:

The course will generalise the simple methods for thermodynamics and fluid mechanics already possessed by the students, and allow them to model engineering systems. The simplifications necessary to make the equations tractable and the methods that can be used subsequently will be covered. An important aspect of the element is the appreciation of the limitations that result from these simplifications. Theory will be applied to the selection and sizing of equipment, and to determining the forces imposed by fluid flows on structures.

By the end of the course, students should be able to:

- Recognise and describe the basic frameworks of thermofluids and the characteristics of different types of fluid and energy flows;
- Describe the relationships between different types of flow and energy transfer ( the associated assumptions and fundamental science are important);
- Explain the limitations of the different approaches to calculating flows;
- Analyse engineering problems, such as sizing equipment or identifying fluid forces, by making simplifying assumptions and selecting suitable calculation approaches .
- Implement calculation procedures
- Interpret and report data colleected in the laboratory

- A series of two one-hour lectures for 24 weeks. Support for this will be provided through examples classes where individual consultation will be available, plus demonstration of solutions on the board. At the end of the lectures for each topic, students should have consolidated and enhanced the lecture material by background reading and review of the lecture, and by course work. Revision lectures are given in term 3.

- Students are strongly recommended to work at the examples sheets throughout the year and supplement the lecture material by independent study of texts.

- The handouts for each lecture will usually include: objectives and contents of the lecture, necessary equations, nomenclature, and relevant pages in the course text. Copies of difficult diagrams are also given to students. Students are expected to make their own notes, and supplement these from the recommended course text.

- Formative example sheet style coursework questions in Thermodynamics will be given to students in weeks 8, 15 and 20 (approx). Each student has his or her own set of independent parameters. One week is allowed to complete each piece of coursework.

- Two laboratory investigations will be assessed through the completion of reports.

Three-hour written examination (90%) (LOs 1-5); coursework comprising 2 laboratory reports and exercises (10%) (LO6)

The laboratory investigations are compulsory. After the laboratory exercises students will be required to submit a piece of written work.
