동압 데이터의 감쇠계수를 활용한 연소 안정마진 실시간 평가 코드 개발
Code Development for Online Assessment of Combustion Stability Margin by Utilizing Damping Ratios of Dynamic Pressure Data
초록
Combustion stability margin of a model gas turbine has been assessed by utilizing damping ratios of measured dynamic pressure data. It is known that acoustic oscillations in combustion chambers can be described as a superposition of nonlinearly interacting oscillators. Based on this theoretical background, CSMA (Combustion Stability Margin Assessment) code has been developed. The code has been employed into a model gas turbine combustion experiment, focused on the combustion instability, to show its capability to determine the damping ratio of measured dynamic pressure and further to assess combustion stability margin of the experiment, and turned out that the code works well.
