108 The effect of nitrogen in oxidizer on flow field of high-pressure oxygen combustion

Abstract

High-pressure oxygen combustion is important to realize low emission and high load combustion in general combustors such as jet engine in aircraft. We designed a combustor which make it possible to perform high-pressure experiment. We mix nitrogen into oxidizer of oxygen combustion and measure flow field with LDV to investigate the effect of nitrogen in oxidizer on flow field of high-pressure oxygen combustion. We confirmed the various differences between oxygen combustion and oxygen combustion with nitrogen.
