    New paper on Spallation!

    Highlights

    • Particle tracking velocimetry conducted on particles shedding from ablative thermal protection system materials.
    • Tests indicate spallation unaffected by pyrolysis gas formation, but impact of environment largely felt through effects due to gas composition.
    • Effect of sample geometry suggested that surface shear stress plays a role in spallation particle shedding into the flow.
    • An approach was devised to estimate particle diameter based on the acceleration of the particles once they left the material sample.
    • Particle diameters were in the range expected for formation from both individual fibers as well as larger groups of fibers.
