Fundamentals of heat and mass transfer. Concepts of heat exchange and heat exchanger selection. Differential and stage-wise mass transfer processes. Case studies of equipment for heat and mass transfer unit operations.
This courseﾠ covers the fundamental physical phenomena involved in heat transfer and mass transfer processes. Our approach to learning in this course will be (a) to describeﾠ the fundamental phenomena (or mechanisms), (b) to develop mathematical representations of these phenomena (i.e. mathematical models and equations),ﾠ and (c) to apply these principles and models to solve engineering problems, such as design process equipment, and analyseﾠ environmental systems.ﾠ
What is heat transfer?ﾠ The topic of heat transfer covers the generation, use, conversion, and exchanger of thermal energy (i.e. heat) between physical systems. The three core mechanisms involved in heat transfer include conduction, convection, and radiation. Transfer of energy by phase change is also a heat transfer mechanism but that topic is outside the scope of CHEE2040. Heat transfer is driving by thermal gradients from a region of high temperature to another region of lower temperature (i.e. Second Law of Thermodynamics).
Heat transfer is all around you. Some examples of heat transfer processes include your human body constantly ejecting heat to the environment (and you can control this rate of heat transfer by say putting on a jumper/sweater), a solar hot water heater, refrigeration and air conditioning systems, the hot BBQ plate at a CHESS smoko, electronic chips in your computer and smartphone. Industrial process examples include power plants, boilers, heat exchangers in petrochemical plants, food manufacturing, and evaporators. See Chapter 1 of Cengel and Ghajar (2015) for more examples.
What is mass transfer?ﾠ Cengal and Ghajar (2015, p.833) define "Mass transfer requires the presence of two regions of different chemical compositions, and mass transfer refers to the movement of a chemical species from a high concentration region toward a lower concentration one."
Some examples of mass transfer applications include: sustained release of pesticide or pharmaceuticals, bubblers to purify water, CO2 capture processes by gas-liquid absorption (some of these also involve reactions), membrane processes for water desalination, design of an artificial kidney (see Middleman 1998, p.5).

Aims and outcomes
Our aim in CHEE2040 is to understand fundamental heat transfer and mass transfer phenomena, and apply this understanding to analyze heat transfer and mass transfer problems including, their application to creative and effective design of industrial processes and equipment, and to problem-solving in environmental systems. We will apply mathematical models (equations) to describe rate processes for the fundamental transfer phenomena, and use these models in illustrative examples of equipment design and problem solving across a range of process industries and environmental systems.ﾠ

Analyses and attempts solutions consistently and clearly following this recommended protocol, developing a clear and useful schematic representing the scenario, correctly identifying the modes of heat and/or mass transfer involved and/or not involved, and consistently demonstrating the additional competency of clearly showing and explaining the working associated with problem formulation to reach a possible solution. |
| 5 (Credit) |
Demonstrated evidence of proficient achievement of course learning outcomes. Course grade description: Typically 65.0 -74.9% course aggregate score with at least 58.0% in final exam.
