Mechanical engineering: heat and flow

Following an introduction to mechanical engineering and the career and employability opportunities this brings, you’ll study a range of topics relating to thermodynamics, fluid mechanics, heat transfer and sustainability. Theoretical understanding will be supported and applied with relevant practical sessions using wind tunnels at our award-winning OpenEngineering Labs. Industrially relevant skills of heat transfer analysis are taught using ANSYS, the Finite Element Analysis (FEA) software package. In the latter part of the module, you’ll apply the knowledge gained to design the heating and cooling of a low carbon building, as part of the group project.

Modules count towards OU qualifications

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.

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. In the latter part of the module, you’ll also learn more about teamwork, before applying this approach to a group project, to design a low-carbon building. If you have concerns about working in a group, then you’ll be advised to talk these through with your tutor as soon as possible.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • Marking your assignments (TMAs) and providing detailed feedback for you to improve.
  • Guiding you to additional learning resources.
  • Providing individual guidance, whether that’s for general study skills or specific module content.
  • Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.

Assessment

The assessment details for this module can be found in the facts box.

You must use the online eTMA system to submit your tutor-marked assignments (TMAs).

    Ways to pay for this module

    Open University Student Budget Account

    The Open University Student Budget Accounts Ltd (OUSBA) offers a convenient 'pay as you go' option to pay your OU fees, which is a secure, quick and easy way to pay. Please note that The Open University works exclusively with OUSBA and is not able to offer you credit facilities from any other provider. All credit is subject to status and proof that you can afford the repayments.

    You pay the OU through OUSBA in one of the following ways:

    • Register now, pay later – OUSBA pays your module fee direct to the OU. You then repay OUSBA interest-free and in full just before your module starts. 0% APR representative. This option could give you the extra time you may need to secure the funding to repay OUSBA.
    • Pay by instalments – OUSBA calculates your monthly fee and number of instalments based on the cost of the module you are studying. APR 5.1% representative.

    Joint loan applications

    If you feel you would be unable to obtain an OUSBA loan on your own due to credit history or affordability issues, OUSBA offers the option to apply for a joint loan application with a third party. For example, your husband, wife, partner, parent, sibling or friend. In such cases, OUSBA will be required to carry out additional affordability checks separately and/or collectively for both joint applicants who will be jointly and severally liable for loan repayments.

    As additional affordability checks are required when processing joint loan applications, unfortunately, an instant decision cannot be given. On average the processing time for a joint loan application is five working days from receipt of the required documentation.
