The mass flux distribution of spray formed by liquid jet disintegration in subsonic air streams was measured experimentally, and the empirical equation of the mass flux distribution was deduced. The configuration of the upper profile of the spray mass flux in the liquid injection direction above the peak of the profile is different with that of the lower profile. With increasing the momentum ratio of the liquid and the air, the location in the liquid injection direction where the mass flux becomes maximum is elevated, and the maximum mass flux decreases. With increasing momentum ratio, the number of spray droplets formed at the liquid jet surface before the liquid jet breakup point increases, and contour lines of the spray mass flux show a kidney-shaped configuration near the liquid jet breakup point. Downstream of the liquid jet breakup point the maximum mass flux decreases, and the mass flux profile becomes flatter.
