Design and Validation of a High-Bandwidth Fuel Injection System for Control of Combustion Instabilities
The predictive design of fuel injection hardware used for active combustion control is not well established in the gas turbine industry. The primary reason for this is that the underlying mechanisms governing the flow rate authority downstream of the nozzle are not well understood. A detailed …
