Modern rockets operate at supercritical pressures with respect to the propellants. Researchers 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 need 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.
