HEAT TRANSFER AND LABORATORY - 2021/2
Module code: ENG2121
In light of the Covid-19 pandemic the University has revised its courses to incorporate the ‘Hybrid Learning Experience’ in a departure from previous academic years and previously published information. The University has changed the delivery (and in some cases the content) of its programmes. Further information on the general principles of hybrid learning can be found at: Hybrid learning experience | University of Surrey.
We have updated key module information regarding the pattern of assessment and overall student workload to inform student module choices. We are currently working on bringing remaining published information up to date to reflect current practice during the academic year 2021/22.
This means that some information within the programme and module catalogue will be subject to change. Current students are invited to contact their Programme Leader or Academic Hive with any questions relating to the information available.
Heat Transfer: Knowledge of heat transfer is vital for Chemical Engineers. In order to effectively design and operate many unit operations, such as heat exchangers and reactors, a sound understanding of the fundamentals of heat transfer is required. This part of the module is intended to introduce students to the basic mechanisms of heat transfer and to allow them to apply this understanding to the design of heat exchangers.
The laboratory element extends upon the skills developed in FHEQ Level 4 of the degree programmes, with particular attention to investigations that demonstrate and reinforce concepts of several FHEQ Level 5 modules.

The assessment strategy is designed to provide students with the opportunity to demonstrate successful attainment of the full range of learning outcomes covered in lectures and practised in tutorial classes. Where appropriate, the assessments will reflect industrially relevant systems.
Thus, the summative assessment for this module consists of:
- Examination – 65%, 2 hours (LO1 – LO4)
- Coursework (Laboratory) - 35%, comprising of: a Full Investigation Report (15%), a Short Investigation Report (8%) and 3 Results and Executive Summary Reports (3x4%), with the inclusion of additional dissemination elements such as verbal presentations and proposals for new operational / briefing guides. (LO5 – LO8)
Students will receive formative assessment via a series of randomised multiple choice tests on SurreyLearn. Also they will undertake the following formative assessment:
- In-Semester Test (Heat Transfer) – Combination of questions addressing fundamental knowledge (LO1, LO2) with open ended design calculations (LO3)
- Weekly verbal feedback during tutorial classes (LO1 – LO4)
- Verbal feedback during optional drop-in tutorial classes (LO1 – LO4)
- Written feedback on Coursework with full worked solutions published on SurreyLearn (LO1 – LO4)
- Written and verbal feedback on Coursework (LO5 – LO8)
- Demonstrator feedback on equipment operational matters during the course of the laboratory work (LO5, LO6)
- Familiarise students with the mechanisms of heat transfer and with the basic approach to solving steady state and transient heat transfer problems
- Teach performance and design calculation methods for a range of heat exchanger types.
- Introduce heat flux calculations for conduction, convection and radiation transfer mechanisms
- Analyse heat transfer in pipe flow
- Develop the practical skills necessary for problem solving, analysis, and technical dissemination through laboratory experimentation.
- Further underpin the many theoretical aspects of the degree programmes through practical experimentation.

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
- Present the fundamental material in lectures in the context of industrially relevant examples
- Allow students to practice the techniques developed in lectures through extensive tutorial examples. The solution of these problems will involve both guided study in tutorial sessions and independent study.
- Provide the students with basic guidance on the laboratory task with the support resources to facilitate creative and critical thinking and an explorative approach to the work.
- Provide students with repetitive practice and feedback on report dissemination.
The learning and teaching methods include:
- Lectures – 2 hours per week for 11 weeks
- Tutorials – 1 hour per week for 11 weeks
- Laboratory work 12 hours laboratory classes in 2 hour sessions
- Guided work 12 hours guided work in support of the labs (2 hours per lab)
- Independent learning – 6.8 hours per week for 12 weeks
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
