Unit description Unit description
The unit is designed to provide a comprehensive treatment of heat and mass transfer and a fundamental understanding of the different heat transfer modes (conduction, convection, and radiation) in practical engineering fields of interest. The students will learn how to apply the principles of heat transfer using numerical techniques to analyse existing thermo-fluid systems, and to develop designs which improve existing thermo-fluid systems. Knowledge from this unit together with the principles of Thermodynamics (MECH301) will help promote and develop sustainable engineering applications through their analysis and design as problems in heat and mass transfer.

Learning Outcomes

On successful completion of this unit, you will be able to:

  • The student will be able to identify the characteristics of a heat transfer system and delineate between conduction, convection and radiation processes.
  • The student will be able to apply analytical tools in calculations of heat transfer for ideal and real world problems.
  • The student will gain an understanding of heat exchangers, their design, and their application to industrial problems.
  • Develop experimental techniques, collaborative work and teamwork skills in workshop and laboratories

General Assessment Information

The following conditions apply for satisfactorily passing this course:

1. At least 50% marks overall

2. must submit at least 2 assignments and 1 lab reports

For assignments handed in late the following penalties apply: 0-24hrs -25%, 24-48hrs -50%, more than 48 hrs -100%

Assignments (3)

Three individual assignments will test the student’s understanding of the course material taught up to the point each assignment is distributed. The student is expected to solve problems which test both the concepts taught as well as the technical capabilities of the students in analysing heat transfer problems. These assignments must be completed individually.

Laboratories (2)

Two individual lab reports written for two unique experiments. The first experiment will demonstrate the operation of heat exchangers.  Students will test different heat exchanger designs, acquire data and compare to theoretical calculations of heat exchanger performance. The second experiment will demonstrate experimental techniques used to take measurements of conduction and convection.

The students will write two individual lab reports discussing their findings and comparing to theory where appropriate. While the laboratories are done in groups, the reports are to be done individually.

Mid Term Test (1)

An in-class 1hr test assessing material delivered between weeks 1 and 7.

Final Examination (1)

Final examination assessing all material delivered throughout the course
