TEC1807 · Principle of thermodynamics

Overview

This unit introduces the foundational principles of thermodynamics, with a focus on the first and second laws and their applications in modern technology and engineering systems. You will explore the fundamental concepts of energy, heat, and work, as well as the ways they are transformed through various thermodynamic processes. The first law of thermodynamics is examined through the principle of energy conservation and its application to systems such as engines, power plants, refrigeration systems, and renewable energy technologies. The second law introduces the concepts of entropy, efficiency, and the natural direction of energy transfer, with emphasis on irreversibilities and thermodynamic cycles. Throughout the unit, you will apply thermodynamic principles to practical and industry-relevant scenarios, including evaluating the performance of energy systems, optimising vehicle engines, and improving energy efficiency in technological devices. By integrating theoretical knowledge with real-world applications, this unit develops your analytical and problem-solving skills while providing a strong understanding of the role thermodynamics plays in the design of sustainable, efficient, and innovative technologies for future advancements.
