CHE2163 - Heat and mass transfer - 2019

• 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.
• Calculation of overall heat transfer coefficient and heat transfer area using Log Mean Temperature Difference (LMTD) and Number of Transfer Unit (NTU) method.
• Gain an understanding of molecular diffusion in gases, solids, and liquids, and convective mass transfer between two fluids in contact, and develop methods to use these concepts in problem solving.
• Perform experiments to illustrate the concepts of heat and mass transfer.

At the successful completion of this unit you will be able to:

1. Determine which modes of heat transfer (conduction, convection and radiation) and/or mass transfer (diffusive and convective) are occurring in a given problem
2. Identify key assumptions (e.g. steady state vs transient) that lead to a solution procedure.
3. Formulate solutions for common engineering problem using a combination of analytical equations, dimensional analysis, and empirical correlations
4. Critically analyse the solution with respect to clarity (communicating the solution to engineers and managers), effects of errors, validity of assumptions, and how the solution(s) can be used to provide operational advice.
5. Conduct self-directed learning using common textbooks, online tools and reference texts, in order to prepare for laboratory sessions and assignments (including preparation for self-directed life-long learning beyond tertiary education).

NOTE: From 1 July 2019, the duration of all exams is changing to combine reading and writing time. The new exam duration for this unit is 2 hours and 10 minutes.

Continuous internal assessment: 50%

Examination (2 hours): 50%

Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

3 hours lectures, 2 hours practical classes and 7 hours of private study per week, and 4 hours of laboratory classes during the semester.
