Overview
Thermofluids is the study of fluids (liquids and gasses) and their interaction with the environment. Engineers take advantage of the ability to perform tasks by changing the temperature of fluids or forcing them to flow. Through an understanding of how these processes occur, engineers are able to refine current practices and devise new systems which perform more efficiently, which is beneficial to the environment and the economy. This course builds upon MEC2106 Introduction to Thermofluids by studying more complex systems and introducing more advanced analysis techniques to investigate the performance of individual components.
The analysis of thermofluids is based around forces and energy: this is how fluids interact with other fluids and solids as part of their environment. A consequence of every process is an increase in the chaos in the universe; the implications for this in engineering systems are explored. The effects of friction on subsonic fluid flow are investigated, while the nature of heat transfer transmitted by solids and fluids is explored in detail for practical situations.
Course learning outcomes
On successful completion of this course students should be able to:
- discriminate between systems which behave realistically and those which do not, applying this knowledge to analyse real engineering systems;
- analyse the effects of viscosity on the behaviour of fluids in subsonic flows;
- analyse the heat transfer through fluids and solids under static and dynamic conditions.

Student workload expectations
To do well in this subject, students are expected to commit approximately 10 hours per week including class contact hours, independent study, and all assessment tasks. If you are undertaking additional activities, which may include placements and residential schools, the weekly workload hours may vary.
