Heat transfer is the area of study that focuses on the movement of thermal energy from one object or substance to another due to a temperature difference. This transfer can occur through mechanisms such as conduction, convection, and radiation. Heat transfer plays a fundamental role in various engineering and scientific applications, including the design of heating and cooling systems, the optimization of thermal insulation, and the study of energy conversion processes. Researchers in this field aim to understand and improve heat transfer processes to enhance efficiency, performance, and safety in a wide range of industrial and environmental systems.
