Ballistic Imaging for Dense Spray Diagnostics in Harsh Chemically Reacting Environments
Agency / Branch:
DOD / USAF
During the Phase I effort, we propose to evaluate the feasibility of performing ultrafast-laser-based ballistic imaging for studying liquid hydrocarbon and oxygen injection characteristics for possible application in bi-propellant rocket engines. Ballistic imaging has the potential to circumvent the difficulties associated with propagating light through dense media. Through the combined use of ultrafast time gating, polarization gating, and spatial filtering, photons that propagate without interference (i.e., ballistic photons) are preferentially detected over photons that undergo significant beam steering or multiple scattering. During the Phase I effort, we will (1) assemble an ultrafast-laser-based ballistic imaging system, (2) demonstrate the feasibility of using this technique for liquid oxygen and hydrocarbon injection, (3) evaluate the use of ballistic imaging using a Monte-Carlo simulation for laser-spray interaction, and (4) develop a strategy for implementation in a demonstration bi-propellant rocket engine combustion system in collaboration with the DOD and an industry partner.
