Laws of Thermodynamics and Their Applications in Heat Engine

Abstract

Thermodynamics is a fundamental branch of physics that governs the behavior of energy and heat in various systems. This paper explores the key principles of thermodynamics and their applications in internal combustion engines and gas turbines. The first law of thermodynamics, which states that energy cannot be created or destroyed but can only change forms, is fundamental to understanding energy transfer in these machines. The second law of thermodynamics introduces the concept of entropy and explains the direction of heat flow. We have discussed the applications of the laws in design and operation, such as improving performance and efficiency. We look forward to the development of the applications in the future.
