Abstract

This research aims to improve gas turbine performance and suppress compressor rotating stall and surge. The effect of water spray at the compressor inlet on the stable operating range and performance of the gas turbine was examined. In gas turbines, combustion is a complex phenomenon that involves a variety of physical and chemical processes, changes in flow rate, turbulence intensity, and operating pressure and temperature variations. These phenomena cause inappropriate behaviors, like abrupt acceleration, stopping, and explosions, in continuous combustion processes within the combustion chamber. The blow-by phenomenon in aviation engines is greatly impacted by problems with combustion instability and flame continuity, especially at high altitudes. These engines must operate at low flame temperatures and in lean, difficult-to-ignite mixture conditions due to emissions regulations. This increases the opportunities and potential for extinguishing fires, contributing to the development of blow-off conditions. There isn't a comprehensive theory for how gas turbines burn, so this study must rely on empirical correlations and basic models.
