Statement of Need: Modern rockets operate at supercritical pressures with respect to the propellants. Need to understand mixing and combustion beyond liquid, gas states. Shear coaxial injectors are a common choice for cryogenic liquid rocket engines. Interactions of transverse acoustics with injector s own modes and mixing needs to be understood for combustion instability. Need to understand differences in response to pressure and velocity nodes. Understand what non-dimensional numbers capture the mixing of typical injectors. Characterize how geometry affects mixing.
