Thermal effects is the academic field investigating the generation, transfer, and consequences of thermal energy within physical systems. It encompasses the study of phenomena related to temperature changes, heat flow, and the resulting thermal states, particularly those arising from energy conversion processes. This field investigates the mechanisms of heat production, distribution, and dissipation, alongside the induced changes in material properties, system performance, and environmental interactions. Understanding thermal effects is critical for the design, control, and optimization of systems where energy management and temperature regulation are paramount, such as power generation, industrial processes, and environmental studies.
