ADVANCED FLUID MECHANICS AND THERMODYNAMICS - 2024/5

Module Overview

The FHEQ Level 5 treatment of thermofluids builds on the material taught at FHEQ Level 4. It is presented in three linked sections: Thermodynamics, Heat Transfer and Fluid Mechanics. The Thermodynamics section introduces the second law of thermodynamics, entropy and associated concepts. These are used in understanding cycles and processes, and consideration of common engine cycles.
The Heat Transfer section gives a solid grounding in aspects of heat transfer that are essential for engineers. It covers. fundamental transfer mechanisms for steady state problems. Heat transfer coefficient evaluation and pipe flow problems are considered. Heat exchanger design and simple radiation exchange problems are introduced.
The Fluid Mechanics section considers incompressible, inviscid and viscous flow, and introduces compressible flow. Boundary layer theory is related to external flow around streamlined bodies, such as cars and aeroplanes in high Reynolds number flows. Bluff bodies with flow separation are also considered. Compressible flow theory is related to
aerospace and other applications where flow velocities are high and fluid density changes become significant.

Assessment pattern

Alternative Assessment

The live Industry Lecture will not be available in the LSA period, so alternative coursework will be provided,

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of scientific principles, methodologies and mathematics methods as well as the ability to describe particular systems and processes. The unseen examination includes a range of questions testing the learning outcomes described above.

Thus, the summative assessment for this module consists of:

In-semester test - Learning outcomes 1,2,3

Laboratory demonstrations - Learning outcome 2

Examination - Learning outcomes 1,2,3

Written feedback is given on the class test.

 

Formative assessment and feedback

Formative assessment is within tutorials and formative verbal feedback is given in tutorials.

Module aims

• Illustrate the need for a thorough understanding of thermodynamics and heat transfer in overcoming problems associated
  with global warming and energy supply
• Develop understanding of the second law of thermodynamics and its application to internal combustion gas power cycles
• Familiarise students with the mechanisms of heat transfer and with the basic approach to solving steady state heat transfer
  problems and design calculation methods for a range of heat exchanger types.
  
• Provide students with the ability to calculate the drag and heat transfer for flow over a flat plate
• Introduce compressible flow behaviour in converging and diverging nozzles.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:
Introduce thermo-fluid principles through theory with worked examples. This is delivered through lectures, tutorial classes and practical laboratory demonstrations. Tutorial questions complement the lecture material with students expected to
attempt the tutorial questions following the lecture and obtain help and feedback during the tutorial sessions.
The learning and teaching methods include:
Lectures
Tutorials
Independant study

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
