CHE2163 · Heat and mass transfer

Overview

• 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.

Assessment

The Handbook lists an examination for this unit.

Continuous assessment: 50% Final assessment: 50% This unit contains hurdle requirements that you must achieve to be able to pass the unit. You are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final assessment component. The consequence of not achieving a hurdle requirement is a fail grade (NH) and a maximum mark of 45 for the unit.

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.

Requisites

The Handbook lists no prerequisite, corequisite or prohibition for this unit.

Learning outcomes

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).

Workload

The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-6 hours of scheduled learning activities and 6-9 hours of independent study per week. Scheduled activities may include a combination of teacher-directed learning, peer-directed learning and online engagement. Independent study may include associated readings, assessment and preparation for scheduled activities.

Student experience, not official rules. Nothing here changes what the Handbook says.
