Students will be able to apply their knowledge to understand heat transfer systems in practical industries and will be equipped to analyse/design heat transfer systems/surfaces and heat exchangers.
Subject Topics
- Introduction
- One dimensional steady state conduction
- Forced convection
- Free convection
- Radiation
- Heat exchangers
Subject Learning Outcomes (SLOs)
On completion of this subject students will be able to:
- Describe the mechanisms of heat transfer between elements of a system
- Determine the correct assumptions and approximations for tackling practical situations
- Analyse one-dimension conduction problems
Solve problems involving one or more modes of heat transfer- Apply knowledge and useful information gained on design and analysis of heat transfer systems .
- Working in teams to undertake laboratory exercises, analysing and discussing the outcomes and communicate those via professional reports.
Assessment Tasks and Weightings
To obtain a pass grade in this Subject at least 50% overall must be achieved, and at least 40% achieved in the final examination. Students must also refer to the Subject Assessment Details.
Assessment 1 – Lab/Project Concept Report: A team based or individual component report outlining individual or team formation. Team based report outlining formation and member roles, project selection, team and member action plan and a schedule of future activities to achieve the outcome. The report contributes 20% towards the final grade for the subject.
Assessment 2 – Assignments: The assignments are intended to support students achieving the learning outcomes for the Subject and will contribute 20% towards the final grade for the subject.
Assessment 3 – Class Test: The Test contributes 20% towards the final grade for the subject and evaluates progress towards achievement of learning outcomes.
Assessment 4 – Final Examination: The individual components of final examination enable final evaluation of achievement of learning outcomes and contribute 40% towards the final grade for the subject
