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 … For more content click the Read More button below. 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.

Learning outcomes

On successful completion of this unit, you should be able to:

Determine which modes of heat transfer (conduction, convection and radiation) and/or mass transfer (diffusive and convective) are occurring in a given problem

Identify key assumptions (e.g. steady state vs transient) that lead to a solution procedure.

Formulate solutions for common engineering problem using a combination of analytical equations, dimensional analysis, and empirical correlations

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.

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).

Teaching approach

Active learning

Lectures

The lectures are intended to introduce new concepts during the weekly online 1-hour session, followed by applying these concepts to work through guided problem-solving activities. Lecture videos will also be provided. Class notes are available each week via Moodle, and in the lectures, your lecturer will be "filling in the blanks" so that you can follow at a comfortable pace. Please bring these notes with you to the lectures so that when your open book tests/exam comes up, you have a comprehensive and complete set of notes to guide you through the problems.

Practice class allocation

These sessions allow students to attempt new assignment/exam-style problems on each topic, with demonstrators, lecturers and peers available for support. From previous experience, attendance and engagement in these sessions is a leading indicator of final grade - this is because the assessment is focussed on problem-solving ability, and these sessions allow students to practice problem-solving in a consequence-free environment. For Clayton students, there are 2 practice sessions for which students must enrol (in one practice class only) using Allocate Plus. Once a particular session is full, no more students will be accepted unless evidence is shown that timetabling means that is the only session possible.

Laboratory allocation

There are two laboratory sessions to complete - Heat Transfer Lab (weeks 3-8), and Mass Transfer Lab (weeks 9-12). For Clayton students, the group allocation and laboratory schedule is uploaded on the Moodle and the students are required to stay in that group. No movement is possible between the groups unless there are special circumstances for which a prior approval from the unit coordinator has been sought. It is your responsibility to remember when to attend your selected lab class, even if it is several weeks in the future. Students who "forget" to turn up to their allocated lab session will be re-assigned based on availability (maximum of 50% of marks for the lab) but risk not being able to complete the lab component of the unit (i.e. 0% for lab component). For Malaysia students, please refer to Moodle for more information.

Communication, participation and feedback

Monash aims to provide a learning environment in which students receive a range of ongoing feedback throughout their studies. In this unit, it will take the form of group feedback via practice classes, individual feedback, peer feedback, self-comparison, verbal and written feedback, discussions in class, as well as more formal feedback related to assignment marks and grades. You are encouraged to draw on a variety of feedback to enhance your learning. Teaching approach The unit consists of lectures which are used to highlight key concepts and work through real-world example problems. Student engagement and discussion is key. Practice classes are used to implement the theory learned in lectures for problem-solving and working in peer learning groups - if you are comfortable answering the weekly practical class problems, you will be comfortable with the in-class tests, assignments and final exam. Laboratories are used for learning the practical aspects of the heat and mass transfer theory.

Assessment summary

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.

Workload requirements

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.
