Effects of ambient pressure on autoignition of a fuel droplet in supercritical and microgravity environment

An experimental study has been performed under microgravity conditions to obtain the detailed information needed to understand the combustion phenomena of a fuel droplet which autoignites in supercritical gaseous environment. A fuel droplet suspended at the tip of a fine quartz fiber in the cold section of the high-pressure combustion chamber was transferred quickly to be subjected to a hot gas in an electric furnace. This resulted in the...
