Microgravity conditions allow the creation of spherical flames which simplify analysis and reveal behavior that is difficult to study on Earth. Flames like this are yielding valuable information about soot formation and flame extinction.
“Four of ACME’s experiments are designed to improve our understanding of flame behavior for practical use on Earth,” said Glenn’s ACME project scientist Dennis Stocker. “The other experiment is intended to help us understand and improve spacecraft fire safety.”
Coflow Laminar Diffusion Flame will extend the range of flame conditions that can be accurately predicted, especially under conditions where the flame is sooty or could become unstable.
Electric-Field Effects on Laminar Diffusion Flames will investigate how an electric field can be used to control flames, through their naturally occurring ions, to reduce pollutant emission.
Structure and Response of Spherical Flames will aid in predicting the structure and dynamics of soot-free and sooty flames.
Flame Design experiment seeks to expand our understanding of soot inception and control in order to optimize oxygen enriched combustion and the design of robust and soot-free flames.
Burning Rate Emulator experiment is focused on flammability and the selection of materials for use in spacecraft.
