The structure and mixing properties of noncondensing round turbulent air jets in still water was investigated experimentally, considering both subsonic and sonic underexpanded with underexpanded ratios up to 81 jet exit conditions. Measurements included flow visualization, using flash and high-speed motion-picture photography mean void fraction distributions, using deconvoluted gamma-ray absorption measurements mean entrainment velocities, using laser-Doppler anemometry and mean static pressures along the axis, using a static pressure probe. Analysis was also undertaken to help interpret the measurements, based on the locally-homogeneous-flow approximation relative velocity differences between the phases neglected and an effective-adapted-jet approximation for treating the mixing properties of the underexpanded jets.
