摘要

A theoretical and experimental study of the dense-spray region of pressure-atomized nonevaporating sprays is described, emphasizing operation in the wind-induced and atomization breakup regimes. Experiments involved large-scale (9.5 an 19.1 mm injector diameters) water jets in still air. The flows were visualized using flash photography. In addition, the following measurements were made: mean and fluctuating streamwise velocities at the injector exit, mean liquid volume fraction distributions, and mean entertainment rates. The new measurements were used to assess predictions of flow structure based on the locally-homogeneous-flow approximation, i.e., assuming that interphase transport rates are infinitely fast so that relative velocities between the phases are negligible.
