Liquid Oxygen Droplet Combustion

The combustion of liquid oxygen droplets in a hydrogen environment is being studied in a collaboration between the UW, the Center of Applied Space Technology and Microgravity (ZARM) at the University of Bremen in Germany, and the IPHT Leibnitz-Institute for Photonic Technologies in Jena, Germany. This combustion problem is relevant to rocket combustion chambers utilizing cryogenic hydrogen/oxygen propellants. Combustion tests are conducted both in the laboratory and in microgravity using the ZARM Drop Tower. Optical diagnostics are developed in collaboration with the IPHT. The UW is contributing to this research by analytical and numerical modeling of the droplet evaporation and combustion processes. The research is primarily funded by the German Aerospace Center (DLR); the UW portion is supported by the US Fulbright Program.
