An Experimental Study on Combustion Instability Mechanism in a Dump Gas Turbine Combustor
모형 가스터빈 연소기내 연소불안정성에 대한 실험적 연구
Abstract
The knowledge of flame structure is essential for control of combustion instability phenomena. Some results of an experimental study on mechanism of naturally occurring combustion oscillations with a single dominant frequency are presented. Tests were conducted in a laboratory-scale dump combustor at atmospheric pressure. Sound level meter was used to track the pressure wave inside the combustor. The observed instability was a longitudinal mode with a frequency of
