Abstract

A model combustor has been designed and fabricated for studying the combustion characteristics of oxygen (O2)/hydrogen (H2) flames under supercritical conditions. The combustor is designed to allow combustion experiments up to 60 bar, the supercritical pressure condition of O2 and H2. Injectors can be replaced to study various types of flames and the combustion chamber is designed to visualize flames by installing optical windows. Through the preliminary tests, including a high-pressure (up to 60 bar) test using air and combustion tests for coaxial jet flames of liquid oxygen (LO2)/gaseous hydrogen (GH2) at elevated pressure, the reliability of the combustor has been demonstrated.
