General course information Outline and aims In this course, the principles of transport phenomena introduced previously in fluid flow are extended to heat and mass transport. Topics include: Introduction to conductive, convective and radiative mechanisms of heat transfer, Physical origins and rate equations, one-dimensional steady-state heat transfer with heat generation and chemical reactions, composite walls, contact resistance and extended surfaces, introduction to heat exchangers; log-mean temperature difference, effectiveness - NTU methods, Introduction to diffusive and convective mechanisms of mass transfer, Physical origins and rate equations, diffusion coefficients, one-dimensional steady-state mass transfer in common geometries, applications of heat and mass transfers. The aim of this course is to develop your understanding of the various modes of heat transfer and mass transfer phenomena. Problem-solving skills that you have acquired in first year courses are extended with numerical problems that involve: developing and applying methods for the estimation of rates of heat/mass transfer, temperature distributions and concentration profiles; implementing appropriate assumptions to simplify solutions; and critically evaluating different calculation methods. Requisite knowledge and relationships to other courses The topics of heat and mass transfer complement other areas such as material and energy balances (CEIC2000 and FOOD1130), as well as fluid flow (CEIC2001). These courses introduce core chemical and food engineering topics. They relate to the application of scientific knowledge to practical situations typically found in the chemical and food industries. They are also important for plant and equipment design (CEIC3004 and FOOD3801). Target students and career prospects The course is targeted at second year chemical engineering chemical product engineering, and food science & technology students. Course content is also relevant to Mechanical, Civil and Petroleum Engineering. Heat and mass transfer theory is widely used in the design of processes and equipment in the chemical industry. Course Details 6 UOC with 50 h contact hours and a total of 150 h of student effort. The course is offered in Term 2 only.

Student Learning Outcomes At the successful completion of this course you (the student) should be able to: 1. Explain fundamental concepts in heat and mass transfer; 2. Apply various methods for estimating rates of heat/mass transfer involving solid, liquid and gaseous phases; 3. Identify physical property data needed in solving heat and mass transfer problems.

Due Date Rationale and Assessment Criteria Weeks 1-4 To assess understanding of heat transfer topics and to provide feedback. Approx. 20 min duration each. Week 7 Summative assessment for the heat transfer part of the course. Formal exam because it has high reliability and precision. Assessed on the basis of technical accuracy, speed of calculations, clarity of presentation and ability to exercise good engineering judgement. Online exam of approx. 2 hrs. duration. Weeks 7-10 To assess understanding of mass transfer topics and to provide feedback. Approx. 20 min duration each. Exam period Summative assessment for the mass transfer part of the course. Placed in the middle of the semester to remove weight from the final exam. Assessed on the basis of technical accuracy, speed of calculations, clarity of presentation and ability to exercise good engineering judgement. Online exam of 2 hrs. duration.

Resources for Students The recommended text books are: • •

J.P. Holman, Heat Transfer, McGraw-Hill (6th or higher edition preferred). J.M. Coulson & J.F. Richardson with J.R. Backhurst and J.H. Harker, Chemical Engineering Volume 1: Fluid Flow, Heat Transfer and Mass Transfer, Butterworth Heinemann.

Additional materials will be handed out in class and placed on Moodle. You should check Moodle at least twice a week for any messages. Students seeking resources can also obtain assistance from the UNSW Library. One starting point for assistance is: http://www.library.unsw.edu.au/servicesfor/students.html

Teaching Strategies This course is organized into 3hr/week of lectures and 2hr/week of tutorials. The lectures are used primarily for introducing the relevant theory on heat and mass transfer. A set of numerical problems has been prepared for each tutorial class. Regular quizzes will be conducted during the tutorials to assess your understanding of the topics and to provide you with feedback on your progress.

The rationale behind the approach to learning and teaching Heat and mass transfer theory is widely used in the design of processes and equipment in the chemical industry. Successful design requires a capacity for critical thinking and this can be facilitated through evaluation of different calculation methods. A heavy emphasis is therefore placed on solving numerical problems to reinforce the theory covered in the lectures. Each tutorial consists of a series of numerical problems with varying degrees of difficulty. Detailed solutions will be provided, as well as summaries of the lecture content, to encourage independent learning. A key concept introduced in this course is the analogy between heat and mass transfer. Please note that the lecture summaries are intended as a guide to the topics and to assist with study preparation. To facilitate deeper learning, students are expected to consult the recommended textbooks for more detailed explanations.

Academic Honesty and Plagiarism What is Plagiarism? Plagiarism is the presentation of the thoughts or work of another as one’s own.*

Examples include:

direct duplication of the thoughts or work of another, including by copying material, ideas or concepts from a book, article, report or other written document (whether published or unpublished), composition, artwork, design, drawing, circuitry, computer program or software, web site, Internet, other electronic resource, or another person’s assignment without appropriate acknowledgement; paraphrasing another person’s work with very minor changes keeping the meaning, form and/or progression of ideas of the original; piecing together sections of the work of others into a new whole; presenting an assessment item as independent work when it has been produced in whole or part in collusion with other people, for example, another student or a tutor; and claiming credit for a proportion a work contributed to a group assessment item that is greater than that actually contributed.† For the purposes of this policy, submitting an assessment item that has already been submitted for academic credit elsewhere may be considered plagiarism. Knowingly permitting your work to be copied by another student may also be considered to be plagiarism. Note that an assessment item produced in oral, not written, form, or involving live presentation, may similarly contain plagiarised material. The inclusion of the thoughts or work of another with attribution appropriate to the academic discipline does not amount to plagiarism. The Learning Centre website is main repository for resources for staff and students on plagiarism and academic honesty. These resources can be located via: www.lc.unsw.edu.au/plagiarism The Learning Centre also provides substantial educational written materials, workshops, and tutorials to aid students, for example, in: correct referencing practices; paraphrasing, summarising, essay writing, and time management; appropriate use of, and attribution for, a range of materials including text, images, formulae and concepts. Individual assistance is available on request from The Learning Centre. Students are also reminded that careful time management is an important part of study and one of the identified causes of plagiarism is poor time management. Students should allow sufficient time for research, drafting, and the proper referencing of sources in preparing all assessment items. * Based on that proposed to the University of Newcastle by the St James Ethics Centre.
