    John,

     

    Thanks for the original post.  I saw an abstract to SCITECH this year and it made me wonder if there were others working the topic.  Does anyone know of any research being done on inside fuel tank O2 sensors?

     

    Thanks,

    Steve

    Modeling and simulation of hydrodynamic spurt, or the fluid deposition process resulting from projectile impacts of fuel tanks, specifically the liquid jet generated prior to cavity collapse (e.g., "pre-spurt" / "Shallow Jet Spurt").

    I fully support Adam's thoughts on liquid spurt. This was actually also one of the recommendations for future work identified in a review paper on HRAM, which was recently accepted for publication:
