Engineers specializing in the design and optimization of these systems became known as thermal engineers, as they dealt with the conversion and management of heat energy.
In 1824, French physicist Sadi Carnot published his groundbreaking work titled 'Réflexions sur la puissance motrice du feu' (Reflections on the Motive Power of Fire). This work, often referred to as Carnot's Thermostatique, laid the foundation for thermodynamics and introduced the concept of heat engines. Carnot's theories greatly influenced the development of thermal engineering.
In 1865, American scientist Josiah Willard Gibbs introduced the field of chemical thermodynamics by presenting his paper 'On the Equilibrium of Heterogeneous Substances.' This marked a significant advancement in thermodynamics by extending its principles to chemical reactions and mixtures. The emergence of chemical thermodynamics further expanded the scope of work for thermal engineers, as now they had to consider the thermodynamic properties of chemical substances.
In 1843, British physicist William Thomson, also known as Lord Kelvin, introduced the concept of an absolute temperature scale based on the principles of thermodynamics. The Kelvin scale, which set absolute zero as the point of zero temperature, provided a new way to measure and understand heat. Lord Kelvin's work revolutionized thermal engineering, enabling more precise calculations and analysis.
During the mid-19th century, the Industrial Revolution brought about significant advancements in engineering and manufacturing. The growing demand for efficient energy utilization led to the emergence of thermal engineers who specialized in designing and optimizing heat engines, boilers, and other heat-based systems.
In the 1870s, the first laws of thermodynamics were formulated, laying the groundwork for understanding the relationship between heat, energy, and work. Rudolf Clausius, Josiah Willard Gibbs, and others contributed to the development of thermodynamics, providing crucial insights into heat transfer and energy conservation. These laws became fundamental principles in the field of thermal engineering.
In 1897, the American Society of Mechanical Engineers (ASME) was founded with the aim of promoting advancements in mechanical engineering. As thermal engineering was an integral part of this discipline, the ASME played a crucial role in fostering the growth of thermal engineering as a profession.
