One of the fundamental concepts in technical thermodynamics is the concept of energy. Energy exists in different forms, such as thermal, mechanical, electrical, and chemical. The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, but it can only be transferred or transformed from one form to another.

The second law of thermodynamics deals with the direction of energy flow and the efficiency of energy conversion processes. It states that in any energy conversion process, there will always be a decrease in the overall usefulness of energy known as entropy. This law establishes the limits and constraints in energy conversion, leading to the concept of irreversibility.

Applications in Engineering

Technical thermodynamics has numerous applications in various engineering fields. Here are a few notable ones:

1. Power Generation

In the field of power generation, thermodynamics plays a crucial role in designing efficient and sustainable energy conversion systems. Power plants, whether they run on fossil fuels, nuclear energy, or renewable sources, heavily rely on thermodynamics principles to optimize energy production, improve efficiency, and minimize environmental impact.

2. HVAC Systems

Heating, ventilation, and air conditioning (HVAC) systems are essential in maintaining comfortable indoor environments in buildings and vehicles. Technical thermodynamics helps in designing HVAC systems that efficiently transfer and regulate heat, ensuring optimal comfort and energy efficiency.

3. Automotive Engineering

Thermodynamics is vital in designing and optimizing automotive engines, cooling systems, and exhaust systems. Engineers use thermodynamics principles to improve fuel efficiency, reduce emissions, and enhance performance.

4. Chemical Process Industries

The chemical industry heavily relies on thermodynamics to design and operate efficient chemical processes. Understanding thermodynamic properties and phase equilibria is vital in determining reaction conditions, optimizing reactant ratios, and maximizing product yield.

5. Renewable Energy Systems

With the growing demand for clean and sustainable energy, technical thermodynamics is crucial in the design, analysis, and optimization of renewable energy systems such as solar panels, wind turbines, and geothermal power plants. Engineers need to understand energy conversion efficiency, storage, and utilization to harness renewable energy effectively.

Technical thermodynamics forms the backbone of engineering principles and applications. Its understanding is essential for engineers in designing, analyzing, and optimizing energy systems. From power generation to automotive engineering and chemical process industries, thermodynamics plays a vital role in enhancing efficiency, sustainability, and performance.

By grasping the basics of technical thermodynamics, engineers can unleash their potential in creating innovative solutions for a more energy-efficient and environmentally friendly future.

The book covers the classical areas of technical thermodynamics: The first part deals with the basic equations for energy conversion and idealized fluids. The second part deals with real fluids, which can be subject to a phase change, for example. Furthermore, thermodynamic mixtures of fluids are considered, e.g., humid air and gas mixtures. In the last part of the book, combustion processes and chemical reactions are presented and thermodynamically balanced. In each chapter, there are examples and exercises to deepen the theoretical knowledge. Compared to the first edition, the topic of thermodynamic state diagrams has been greatly revised. State diagrams of relevant refrigerants have been added as well as a formulary. The section on chemically reacting systems has been expanded and thoroughly revised. In the basic chapters, tasks and examples have been added to consolidate the understanding of the subject. The book is aimed at students of mechanical engineering and professional engineers.
