Rationale and Purpose of the Module:

The purpose of this module is to provide students with the knowledge to use theory from modules such as Heat Transfer and Thermodynamics to solve real life engineering problems of a thermo fluidic nature.

Syllabus:

1. Review of fluids, heat transfer and thermodynamics 2. Pipe/duct flow and pressure drop: - Pressure drop/friction factor for laminar/turbulent developed/developing flow in circular and non-circular ducts - Heat transfer correlations for laminar/turbulent developed/developing flow in circular and non-circular ducts - Worked examples of calculations for the above 3. Pump/fan design, performance and selection: - Types of fans/pumps and their applications - Fan/pump design theory - Performance characteristics - Worked examples for sizing and selecting pumps and fans 4. Heat pipes - Types of heat pipes and their applications - Heat pipe design theory - Heat pipe performance characteristics - Worked examples for sizing and selecting heat pipes 5. Refrigeration - Vapour cycle heat pumps - Thermoelectric heat pumps 6. Heat exchanger design and selection -Types of heat exchangers and heat exchanger applications - Heat exchanger theory: LMTD and effectiveness/NTU methods - Correlations for heat exchanger pressure drop and heat transfer - Worked examples for sizing and designing heat exchangers 7. Thermal/fluidic systems design: - Worked examples on the use of a range of heat transfer equipment for designing solutions to thermo-fluid problems 8. Use of standards in thermo-fluidic systems design

Learning Outcomes:

Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)

At the end of this module, students will be able to identify and apply established thermo-fluidic mathermatical tools and methods to: - Determine the performance of thermo-fluid based systems - Design optimised solutions to thermal and fluidic engineering problems, using standards where appropriate.

Affective (Attitudes and Values)

Students will develop an appreciation of typical industrial thermofluidic problems and how to collaborate with others to solve such problems.

Psychomotor (Physical Skills)

None.

How the Module will be Taught and what will be the Learning Experiences of the Students:

This module will be geared towards making the students knowledgeable on how to use theoretical expertise they have gained from previous modules to solve real world engineering problems. To this end, the relevant theories will be revised, new theoretical concepts will be delivered through lectures, and the students will be presented with a series of worked examples which will be solved using the fundamental theoretical concepts. The students will be encouraged to be proactive in solving these problems. Coursework will be assigned to the students. This will require the students to develop solutions to real world engineering problems. The projects will be group based, and so it will be necessary for the students to call upon and develop their collaborative skills. At the end of the semester, the students will articulate their design solutions to their peers and module leader. A percentage of their overall grade will be based on this presentation. The module leader's research background is in the area of fluid mechanics, heat transfer and thermodynamics, and aspects of this research background will be incorporated into the material delivered during lectures. Worked examples and coursework will be also based on industrial and research problems encountered by the module leader.
