Module description

From the heating of a space shuttle as it re-enters the atmosphere, to the workings of engines in hybrid cars, to writing data onto MP3 music players, a vast amount of technology that surrounds us involves moving fluid and heat around.

In many engineering applications as well as in nature, thermofluid phenomena are the main process by which systems operate. Examples include the flow of blood through the heart or the deposit of chocolate into a mould. This module introduces the theory and practice of engineering fluid mechanics, thermodynamics and heat transfer; progressing you to the next level of studying fluid flow and energy. You will explore aspects such as flow in pipes and channels as well as examining turbines and the mathematical modelling of fluid dynamics in general. Course-work covers tasks such as designing a pump-type network to propel water to a reservoir, enabling you to practise the theory explored on the flow of water and challenging you to design a computational model using Excel.

By the end of this course you will have the skills to analyse engineering systems involving internal and external flows, use tables and charts of fluid dynamic, thermodynamic and physical properties, perform basic calculations for thermodynamic operations, and you'll be confident in designing simple heat transfer equipment and water pump technology. This is a pre-requisite for the 3rd year modules: "Thermofluids and Energy Conversion" and "Computational Engineering".

Pre-requisite module: ECM1102

Module aims

To introduce students to the theory, principles and practice of engineering fluid mechanics, thermodynamics and heat transfer, and to prepare for advanced courses in these areas.

This module covers Specific Learning Outcomes in Engineering, which apply to accredited programmes at Bachelors/MEng/Masters level. These contribute to the educational requirements for CEng registration (as defined under the UK Standard for Professional Engineering Competence – UK-SPEC).

This module correlates to references U1, U2, U3, E3, D2, D6, S1, P1, P2 and P4.These references are indices of the specific learning outcomes expected of Bachelors/MEng/Masters candidates set out in UK-SPEC, codified with reference to systems used by professional accrediting institutions. A full list of the standards can be found on the Engineering Council's website, at http://www.engc.org.uk

Re-assessment notes

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.
If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 40% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
