This course provides a comprehensive introduction to heat transfer fundamentals and their applications. The course introduces students to the analysis of steady-state and transient one- and multi-dimensional heat conduction. The course considers the analysis of heat transfer by convection using empirical and boundary layer approximations. Radiation heat transfer is considered with applications to multi-body radiation.

Contribution to Professional Competencies

Heat transfer is an essential engineering science.
Deep learning is much more important than memorizing equations.
Understanding the heat transfer phenomena and the thermal system modelling approach is more important than finding the right equation.
Heat transfer is necessary for process and product design, but this class focuses much more on the engineering science you need to bring effective thermal design into any project.

Learning Outcomes

1. Understand a thermal system, develop the schematic diagram for the system, and apply energy balance and heat transfer models to develop governing equations.
2. Set up and solve for heat transfer rates as a function of geometry and materials in 1-D conduction using various tools:
   i. Material Properties
   ii. Fourier’s Law
   iii. Circuit Analogy
3. Estimate heat transfer from Extended Surfaces, Radial Geometry, and involving Energy Generation.
4. Construct a transient heat transfer analysis, testing for the lumped capacitance approximation and understanding the assumptions.
5. Understand the approach for setting up numerical analysis of heat transfer.
6. Understand a thermal system with convection heat transfer, construct a schematic diagram for the system, characterize the geometry and flow conditions, and apply the appropriate convection models:
   i. Boundary layer effects, laminar and turbulent flow
   ii. Similarity solutions and non-dimensional parameters
   iii. Reynold’s analogy
   iv. Boundary conditions – derivation of energy balance
   v. Use convection correlations for Nusselt Number
7. Understand and model external forced convection heat transfer.
8. Understand and model internal forced convection heat transfer.
9. Understand and model natural convection heat transfer.
10. Understand the phenomena of boiling and condensation.
11. Understand heat exchangers and carry out analysis to select and size heat exchangers for liquid-liquid, liquid-gas, gas-gas, and condensers and boilers.
12. Understand key aspects of radiation heat transfer and solve simple problems. Understand radiative properties and models like black body, surface emission and radiosity.
13. Understand and estimate view factors and compute radiation exchange between grey surfaces.

Additional Course Outline Information

Academic integrity

* Harassment of any sort will not be tolerated.  Each UC student is here to learn and to experience a friendly and supportive community.
* It is every student's right to expect: respect and courtesy from staff and other students, including freedom from harassment of any sort; fair treatment; the ability to speak out about any issues that concern them, without fear of consequences for their safety and well-being.
* Furthermore, each student has the responsibility to: respect the rights and property of others; attend to their own health and safety, and that of others; and behave in a manner towards each other that does not reflect badly on the student body or the University.
* If you, or someone you know, has experienced harassment, please talk to your lecturers, directors of study, or head of department.

Dishonest Practice
* Plagiarism, collusion, copying, and ghost writing are unacceptable and dishonest practices.
* Plagiarism is the presentation of any material (test, data, figures or drawings, on any medium including computer files) from any other source without clear and adequate acknowledgment of the source.
* Collusion is the presentation of work performed in conjunction with another person or persons, but submitted as if it has been completed only by the named author(s).
* Copying is the use of material (in any medium, including computer files) produced by another person(s) with or without their knowledge and approval.
* Ghost writing is the use of another person(s) (with or without payment) to prepare all or part of an item submitted for assessment.

Do not engage in dishonest practices. The Department reserves the right to refer dishonest practices to the University Proctor and where appropriate to not mark the work.
The University regulations on academic integrity and dishonest practice can be found here.
