In this module, you’ll study thermodynamics, fluid mechanics, heat transfer, and sustainability. Theoretical understanding is supported and applied with practical experiments conducted individually and in pairs (using expansion of a perfect gas equipment and wind tunnels) in our . During your study, you’ll learn industrially relevant skills of heat transfer analysis using ANSYS, the Finite Element Analysis (FEA) software package. As part of a group project, you’ll apply the knowledge gained to design the heating and cooling of a low-carbon building.
What you will study
T229 has been designed in three parts; each part is presented both as a printed book with associated online activities. Part 1 focuses on thermodynamics; Part 2 covers fluid mechanics; Part 3 is about heating, cooling and sustainability.
Part 1: Thermodynamics
You’ll consider different forms of energy and how it transforms from one to another. You’ll then discover the limits to these transformations, and the directionality of these processes before learning how heat energy can be harnessed to do mechanical work using a heat engine. This understanding will then be applied to both steam turbines for power generation and jet engines for transport. The reverse process, the heat pump is introduced, as the basis of the refrigeration cycle. Its usefulness in both geothermal power and food preservation is explained.
Part 2: Fluid mechanics
This part looks at the behaviour of liquids and gases moving in a wide range of situations, from domestic plumbing to hurricanes and from jet engines to hydraulic braking systems such as that found in various forms of transport. You will learn how physical and mathematical models help engineers to understand the behaviour of fluids and to solve real-world problems.
Part 3: Heating, cooling and sustainability
You’ll apply your knowledge to design the heating and cooling of ‘low carbon’ buildings and will learn about heat transfer mechanisms within buildings – including radiators, insulation and heat exchange mechanisms. You’ll consider the role of ;engineers in reducing greenhouse gas emissions in the context of global climate policies and will be taught how to apply simple Life Cycle Assessment to buildings. Part 3 also introduces the theory behind effective teamwork and applies this to a group project to design a low-energy and low-carbon building.
Throughout the module there will be opportunities to complement and enhance theoretical knowledge by carrying out a number of relevant experiments. In Parts 1 and 2, you’ll remotely access our OpenEngineering Laboratory to carry out experiments and acquire data in real time. In Part 3, you’ll gain skills in heat transfer analysis by exploring the use of the industry-standard finite element analysis (FEA) software package, ANSYS. If you have concerns about working in a group, talk these through with your tutor as soon as possible.
Entry requirements
There are no formal entry requirements to study this module.
However, we recommend you’ve passed one of the following modules:
The module assumes a level of mathematics skill and prior knowledge which you’ll get from successfully completing one of the modules above. It assumes, and builds on, existing knowledge and skill in the use of trigonometry; differential and integral calculus; vectors; polar coordinate systems; and complex numbers.

Preparatory work
Core engineering A (T271) and Core engineering B (T272) are ideal preparation for this module. We highly recommend you’ve at least studied T271 before studying T229.
What's included
- Access to the module study materials via the module website.
- Three printed module books and a handbook.
Module material is provided in three printed books and two OEL instruction booklets along with associated online activities on the T229 module website. In order to successfully study this module, you need to access both the online and printed materials. A module map and study planner are available for you to use when planning your study.
The module map shows the overall structure of the module and the key assessment dates, with each week displaying detail of what you will be studying. Each week the study planner has an essential overview, which shows what needs to be studied and the order in which to study the print.
