The Lowdown
Olivier Cleynen has authored a free, open-access textbook designed to provide a comprehensive introduction to engineering thermodynamics. Tailored for university students and future engineers, this resource aims to demystify the physical principles underpinning engines and refrigeration systems, starting from foundational concepts and building progressively to complex applications.
- Fundamental Concepts: Introduces core ideas such as energy, the First Law of Thermodynamics, work, heat, and temperature.
- System Analysis: Delves into quantifying energy transfers within both closed systems (fixed fluid quantities) and open systems (continuously flowing fluids), including discussions on irreversibility.
- Gas and Liquid Behavior: Explores the advantages and limitations of the ideal gas model and basic processes, alongside detailed coverage of phase changes and property calculations for liquids and vapors (like water).
- Thermodynamic Cycles: Explains how heat is converted into work and vice versa, covering the efficiency of various thermal machines including engines, refrigerators, AC units, and heat pumps.
- The Second Law and Entropy: Quantifies the fundamental limits of thermal machines, introduces the Carnot cycle, the absolute temperature scale, and explains entropy's role in predicting process direction and irreversibility.
- Power Cycles: Provides in-depth analysis of steam power cycles (Carnot, Rankine, with modifications like superheating and regeneration) and air-based power cycles (Otto, Diesel, turbojet, turboprop).
- Appendices: Includes useful working documents like Steam Tables, unit conversion guides, a bibliography, and an index.
This textbook stands out with its 59 fully-commented, step-by-step calculation examples and 96 problems with solutions, empowering students to confidently tackle real-world engineering challenges. Additionally, it integrates short historical explorations, connecting major thermodynamic ideas to their origins and technological impact.
