Abstract

The paper presents the theoretical basis for determining the radius of the impact surface and the flow thickness formed on the impact surface of a flat fan sprayer with a semicircular slot for the intra-soil application of liquid mineral fertilizers, its analysis using means of computational fluid dynamics (CFD), and the results of experiments. The use of flat fan nozzles that form a spray band under the soil cavity and along the entire length of the tillage knife provides a highly efficient mixing process of liquid fertilizers with the treated soil (particles) and positively promotes plant maturation. Although the sprayer is designed to apply liquid mineral fertilizer into the soil, it is suitable for surface spraying, as well as for use with a point plow and other industrial purposes such as air humidification and fire prevention. Based on theoretical calculations, the applicable radius of the impact surface of the sprayer are in range of 2.5–4 mm. The effective radius is Ds = 2.5 mm. It was found that the flow thickness does not depend on the slot height (h), however it determines minimum value of h. It is recommended that the slot height be 2-3 times the flow thickness. A uniform atomization occurs only if a uniform flow thickness is ensured on the impact surface.
