In this article, high fidelity simulation of liquid jet in crossflow was carried out to investigate the breakup features and deformation characteristics of liquid column with different nozzles in primary breakup. Water as the jet liquid is injected into crossflow from circular and rectangular nozzles. Air velocity ranges from 40 m/s to 80 m/s. The results indicated that at the smaller air velocity, the surface breakup was mainly affected by the sharp angle of rectangular nozzles. And for all nozzles, the breakup regime of liquid column was very similar due to the reason that the final shape of cross section was similar, which was bow. While the air velocity across the sides of liquid column dominated the surface breakup at the higher air velocity. The transformation of breakup regimes was accelerated as the width of rectangular nozzles increased in the column breakup. In contrast to circular nozzles, for rectangular nozzles the deflection of thin edges on the lateral sides of liquid column was avoided, thus preventing the shrinkage of liquid column during injection. The difference of breakup regime for the nozzles may be due to the difference of air velocity in the flow direction of liquid column. Besides, the difference of windward trajectory between rectangular nozzles with the different widths was decreased as the air velocity increased.

Agricultural sprays produced from the atomization of a nozzle-generated liquid sheet produce a wide range of droplet sizes, which impacts crop coverage and spray drift. While the operating conditions and nozzle type are main factors to achieve optimal droplet sizes, the chemical composition of the sprayed mixture also has substantial effect on the droplet size distribution. Particularly, the presence of surfactants and emulsified oil droplets found in agricultural adjuvants can influence droplet sizes, where surfactants tend to decrease droplet sizes and emulsion droplets tend to increase droplet sizes. However, the coupled, mechanistic level understanding of surfactants and emulsified oil droplets together remains mainly unknown. In this study, model spray systems of water, emulsified mineral oil, and surfactants TritonX-100 (water-soluble) and Span 80 (oil-soluble) at varied concentrations are sprayed through a flat-fan nozzle in a low-speed wind tunnel. A laser diffraction setup is used to measure the size distribution of spray droplets as a function of surfactant and oil compositions. The results show a non-monotonic size dependence on surfactant concentration, and importantly that the sprayed droplet sizes are linked with both the oil emulsion size and the aqueous phase dynamic surface tension and surfactant’s critical micelle concentration. The results also show that the oil phase surfactant has no significant impact on the sprayed droplet sizes. While motivated by the agricultural industry, the new insight into surfactant and oil emulsion synergism on sprayed droplet sizes has potential broader applications in multiphase printing, coating, and painting.

A predictive three-dimensional Eulerian−Lagrangian framework for ammonia spray is suggested, and its evolution characteristics under both normal evaporating and superheated conditions are unraveled. First, a simplified boundary model considering the effects of superheated fluid behaviors within the nozzle on the injection velocity and angle was proposed. The real vapor−liquid equilibrium theory is applied in the evaporation model to improve the prediction accuracy of the phase change. An explosion model with the homogenous nucleation theory was used to simulate the burst process. Then, the spray experiment for the liquid ammonia under varied conditions was conducted, and the high-speed diffused back illumination and schlieren approaches were adopted to measure the spray evolutions. Following that, the simulation results were verified against the experimental data under both normal evaporating and superheated conditions, and good agreements indicated that the suggested framework was feasible to accurately and efficiently simulate the evolutions and morphology of ammonia spray. Finally, the transient evolution characteristics of ammonia spray under various conditions were discussed. The heavy cooling effect of ammonia evaporation makes the initial fuel temperature have a notable effect on its spray penetration and expansion.
