Paper Description

Edit Paper Description Content

Thermal Engineering covers the analysis, modelling and design of heat recovery and utility systems (heating, cooling and cogeneration) for industrial sites with an emphasis on minimising energy demand and its associated emissions. The modelling is further extended with considerations for thermal dynamics (start-up, disturbances, shut-down and control) and equipment operating at part-load. Students learn to harness the power of spreadsheeting to solve real-world, opened-end thermal engineering problems. The paper builds on the second year courses of ENGME221 Engineering Thermodynamics and ENGCB224 Heat and Mass Transfer.

The learning outcomes for this paper are linked to Washington Accord graduate attributes WA1-WA11. Explanation of the graduate attributes can be found at: https://www.ieagreements.org/

Paper Structure

Edit Paper Structure Content

The paper has three lectures and a 2-hour tutorial per week, and a 2-hour lab session most weeks. Students engage in a three-step process of learning, practicing and applying the concepts taught in the paper. Many of the examples and problems are taken from real-world applications to better prepare students for industry. The paper announcements, materials and assessments are communicated and managed using Moodle.
