Abstract


A mathematical model of the process of sputtering chemical fertilizers by means of a deflector spray with flat-flare spraying, whose work is based on the Venturi effect, is proposed. Several operating modes of the atomizer with the adjustment of the flow velocity and the angle of the spraying nozzle are examined by changing the geometric parameters of the nozzle head. The most rational parameters of the flow of the components of the atomized medium, as well as the geometric parameters of the atomizer, are taken into account, taking into account the speed of the aircraft and the effect of the screen from the watering surface.
