unsteady combustion

Unsteady combustion refers to a situation where the burning process varies over time, causing fluctuations in flame stability, temperature, and heat release. Unlike steady combustion, which remains constant, unsteady combustion can lead to vibrations, noise, and pressure pulsing within engines or burners. These fluctuations can impact efficiency, produce emissions, or cause mechanical stress. It often occurs due to variations in fuel flow, air supply, or environmental conditions, making the combustion process dynamic and complex. Managing unsteady combustion is important to optimize performance and ensure safe, efficient operation of combustion systems.
