Fire dynamics is the study of how fire behaves and spreads in different environments. It involves understanding the factors that influence combustion, such as fuel type, temperature, and oxygen availability. By analyzing these elements, researchers can predict how a fire will develop, which is crucial for firefighting and safety measures. Key concepts in fire dynamics include the fire triangle, which consists of heat, fuel, and oxygen. Additionally, the fire tetrahedron adds a fourth element: a chemical reaction. Understanding these principles helps in designing better fire prevention strategies and improving emergency response techniques in various settings, from buildings to wildlands.
