Numerical simulation for spray spatial distribution of swirl nozzle and its target dustfall area prediction.

ABSTRACT: The droplet breakup and distribution of the internal flow field and external spray field of a nozzle were obtained under different pressures. The thickness of the liquid film increased with pressure as a quadratic function. The maximum value of 0.281 mm at 2 MPa decreased to 0.172 mm at 10 MPa, equivalent to 38.8% decrease. The MATLAB was used to obtain the particle size distribution characteristics of the droplets under different pressures. At 2 MPa, droplet breakup dominated the axial interval [0-700 mm]. With the increase of pressure, D₅₀ distribution as a whole continues to decrease, 2-6 MPa change, the particle size reduction is larger, every increase of 2 MPa reduced by about 15%. 6-10 MPa change, the particle size reduction is smaller, every increase of 2 MPa reduced by a
