Brief Handbook Description: This unit of study teaches principles of heat and mass transfer required for chemical and biomolecular engineering. It covers steady and transient conduction and diffusion, convective transport of heat and mass, and radiative heat transfer.

It runs concurrently with CHNG2801 (Fluid Mechanics) to provide students with the tools and know-how to tackle engineering problems related to transport phenomena.

It includes project-based study components including a research project on heat transfer in food processing, a heat exchanger design project using engineering design software and a lab session on operation of a heat exchanger.

The integrated course structure helps students to develop a physical understanding of the underlying transport phenomena and gain the ability to solve real heat and mass transfer problems of engineering significance.
Assumed Knowledge: Ability to conduct mass and energy balances, and the integration of these concepts to solve real chemical engineering problems. Ability to understand basic principles of physical chemistry, physics and mechanics. Ability to use mathematics of calculus (including vector calculus) and linear algebra, and carry out computations with MATLAB and MS EXCEL. Ability to read widely outside of the technical literature, and to synthesise arguments based on such literature. Ability to write coherent reports and essays based on qualitative and quantitative information.
Tutor/s: To be announced.
