CHE2163 - Heat and mass transfer

Leader(s): P Chan

Offered

Clayton Second semester 2009 (Day)
Sunway Second semester 2009 (Day)

Synopsis

Introduce fundamentals and applications of heat and mass transfer. Develop an understanding of the mechanisms and mathematical representation of conduction, convection and radiation heat transfer and convective mass transfer. Gain an appreciation for the analogies between heat and mass transfer using dimensional analysis. Understand and apply concepts of local and overall heat and mass transfer coefficients including boiling heat transfer to simple problems. Gain an understanding of molecular diffusion in gases, solids, and liquids and develop methods to use these concepts in problem solving. Perform experiments to illustrate the concepts of heat and mass transfer.

Objectives

1a. Understand the basic mechanisms of conduction, convection and radiation and the mathematical representations of the corresponding rates of heat transfer
1b. Understand the basic mechanisms of diffusive and convective mass transfer within a phase and the mathematical representation of the corresponding rate of mass transfer.
2. Develop an understanding of the dependence of heat and mass transfer rates on fluid and system properties and geometry
3. Understand the analogy between heat and mass transfer
4. Develop skills in solving engineering problems involving heat and mass transfer such as heat transfer between fluids in contact, radiation to/from surfaces, mass transfer between phases in contact.
5. Understand the application of dimensional analysis to the development of correlations for heat and mass transfer
6. Learn to derive and apply expressions for heat and mass transfer coefficients
7. Understand the basic mechanism of molecular diffusion and its mathematical representation.
