## Description

An introduction to the physics of heat-transfer and mass-transfer that underpin process technologies. The course is taught using a first principles basis to explain the underpinning concepts relevant to heat and mass transfer, and to illustrate similarities and differences between these processes. Examples from every day situations, as well as chemical engineering applications, are used to clarify the concepts taught in class.

This course covered the following topics:

Introduction to Heat Conduction
Introduction to Diffusion
Mathematical Concepts in Heat and Mass Transfer
- Dimensional analysis of PDEs
- Solution of PDEs (numerical, analytical and approximate)

Forced Convection Heat and Mass Transfer
Natural Convection Heat and Mass Transfer
A Simple Heat Exchanger

## Learning Outcomes

• At the completion of this course, students will be able to:
• understand the fundamental principles of heat and mass transfer.
• estimate the magnitude of rates of heat and mass transfer in different situations.
• understand the analogy between heat, mass and momentum transfer and identify the limitations of such analysis.
• understand and be able to apply dimensional analysis to problems of heat and mass transfer.
• formulate and solve ordinary differential equations that describe heat and mass transfer problems.
• build numerical models to describe one- and two-dimensional steady state problems.
• make and test reasonable engineering approximations to simplify complex problems in heat and mass transfer.
• select and apply appropriate correlations to solve heat and mass transfer problems.

## Assessment

Course Policy on Collaboration and Cheating
Solving problems in small teams and collaborative learning when working on assignments is encouraged. However direct copying is plagiarism and will result in zero marks for all students involved. When assessment is distributed, you will be instructed whether the assessment is to be submitted for marking individually or as part of a pair/group. The assignments are mainly a tool to prepare you for the exams. The advice is to try them individually before collaborating in groups.
