HERRERA-PRAT, Mario Ignacio; DE LAS CUEVAS-MILAN, Héctor; GARCIA-FERNANDEZ, Miguel Pelayo  e  TORRES-FUENTES, Raúl Ernesto. Energy Balance in Agricultural Sprayers. Rev Cie Téc Agr [online]. 2021, vol.30, n.2  Epub 01-Abr-2021. ISSN 2071-0054.

Most of the sprayers used in fruit trees are of the type of jet transported, which use an air flow produced by a fan to transfer the pesticide drop to the tree. In the energy balance of agricultural sprayers assisted by air flow, it is proposed that between 50 and 65% of the power in these equipment is used by the fan that produces the air flow. Air stream sprayers produce high pollution due to high levels of drift. Using the Computer Modeling of Fluids (CFD) the aerodynamics of the air flow is analyzed based on the geometric and kinematic parameters of the fan, which allows to determine the air flow with better characteristics. The selected regimens assess the quality of the plant cover, using image treatment methods. In this case, a work regime is achieved that decreases the amount of power required, maintaining the quality of the treatment.
