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 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 course ENGME221 Engineering Thermodynamics and strongly links to ENGCB224 Heat and Mass Transfer.

For BE(Hons) programmes, the paper contributes to achieving the required knowledge profile (ENGWK) and graduate attributes (ENGWA) of the Washington Accord. Each learning outcome indicates the most relevant knowledge profile and graduate attribute by the index number (e.g., ENGWA1).

Paper Structure

Edit Paper Structure Content

The paper has three lectures per week, one tutorial (choose one) and a 2 hour lab session. 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.
