This section covers thermodynamic cycles used in refrigerators and heat pumps, focusing on both gas-based and vapour compression systems. It introduces the Coefficient of Performance (COP) as a measure of efficiency and compares the operation of refrigerators and heat pumps. The section also explores the Bell-Coleman cycle (gas refrigeration) and vapour compression cycles using wet and dry vapour.

This section focuses on the behaviour of compressible gas flows in engineering systems. It begins with the conservation of mass, momentum, and energy in pipes with slowly varying cross-sections and leads to the derivation of the steady flow energy equation for compressible flows. This equation forms the foundation for analysing real-world applications. The section then explores how compressible flow behaves in turbines, compressors, and throttling devices, highlighting key practical consideratio...

This section focuses on the thermodynamics of humid air and its relevance in HVAC systems. It covers specific and relative humidity, enthalpy of wet air, and various temperature definitions. The psychrometric chart is introduced to relate humidity and temperature at atmospheric pressure. It also explores humidity measurement devices, adiabatic mixing of humid air streams, and practical processes involving heating, cooling, humidification, and dehumidification.

This section revisits key thermodynamics concepts from EG2004, focusing on systems and control volumes, the first and second laws of thermodynamics, and thermodynamic processes involving ideal gases. It includes the ideal gas equation of state and isentropic processes, with emphasis on topics most relevant to EM3521 Engineering Thermodynamics.

This section covers thermodynamic cycles for power generation using both vapour and gas systems. It includes the Rankine cycle (ideal and real), with variants like superheating, reheating, and regeneration, using steam tables and diagrams to analyse efficiency. It also explores gas power cycles, focusing on the Brayton cycle for turbines (with and without regeneration), and the Otto and Diesel cycles for internal combustion engines.

This PDF contains complete lecture-style notes for EG2004 Thermodynamics and Fluid Mechanics, aimed at university-level engineering students. It covers all the major topics taught in the course including energy and entropy analysis, open and closed systems, work and heat interaction, thermodynamic cycles (including Carnot, isothermal, adiabatic, isobaric, and isochoric), and fluid behaviour under thermal processes. You’ll also find worked examples using equations like SFEE, Gibbs Free Energy, ...
