Combustion science is the study of chemical reactions that occur when a fuel reacts with an oxidizer, typically oxygen, producing heat and light. This process is essential in various applications, including engines, power generation, and heating systems. Understanding combustion helps improve efficiency and reduce harmful emissions. Researchers in combustion science analyze factors like temperature, pressure, and fuel composition to optimize combustion processes. They also explore different types of combustion, such as premixed and diffusion flames, to enhance performance and safety in industries ranging from transportation to energy production.
