Unit Description and General Aims

The objective in presenting this unit is to provide students with detailed knowledge of heat and mass transfer concepts.

The subject matter covered in this unit will include: an introduction to the fundamental principles and basic laws governing conduction, convection, and radiation heat transfer; heat flow mechanisms; an examination of how fins are designed for maximum efficiency; and, transient temperature charts.

Students will also be instructed on: boundary layer concepts; distinguishing between the physical mechanisms concerning natural and forced convection; dimensional analysis as applied to convection; the basic steps in specifying heat exchanger requirements, selecting an appropriate type for a particular application, and employing LMTD and NTU methods of heat exchanger analysis; drawing analogies between heat and mass transfer mechanisms; and, examining diffusion and convective mass transfer principles in detail.

Project work involving the different aspects of the design and selection of fins, and heat exchangers will also be a component of the unit requirements.

At the conclusion of this unit, students will have been imparted with the requisite knowledge to undertake work utilizing heat and mass transfer concepts such as designing and analysing heat transfer equipment, and specifying and selecting heat exchangers for various applications.
