Ignition and Combustion of Magnesium Particles in Carbon Dioxide

摘要: Metal-CO2 propulsion is less known than in-situ resource utilization (ISRU) technologies. This concept, based on using Martian carbon dioxide as an oxidizer in jet or rocket engines, offers the advantage of no chemical processing for CO2 and thus requires power consumption ISRU alternatives. In this paper, we study burning behavior Mg a atmosphere to assess feasibility Mg/CO2 reactions situ technology energy generation other planets. From experimental results, can see that critical ignition temperature increases with increasing particle size decreases ambient pressure. atmosphere, found complicated sequence interaction modes including pulsating combustion wide range temperatures. The pulsation frequency determined by sample at phases slow heterogeneous between flashes. mechanisms are discussed consideration processes both surface film gas phase.
