DESCRIPTION - summary of the module content

Almost all technology that surrounds us involves processes of fluid flow and heat transfer. In many engineering applications as well as in nature, thermofluid phenomena are the main processes by which systems operate. In a car, for instance, this includes the airflow around the vehicle and through the engine, combustion processes in the engine and heat exchange in the radiator, and also climatic control in the passenger compartment. These processes also are important in civil engineering, for example in designing passive climate control systems for buildings, or sustainable urban drainage systems (SUDS).

 

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. Also, you will be introduced to fundamentals of thermodynamics and heat transfer and explore their application in analysing steam operated power plants and design of heat exchangers. Coursework 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. The coursework also includes calculation of work, power and heat transfer using thermodynamic charts and tables.


Prerequisite module: ECM1102 or equivalent

 

AIMS - intentions of the module

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 will 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".

 

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, E1, E2, E4, D1, D4, D6, S3, S4, P1, P2, P3 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.
