| Popis: | This article analyzes flow and deposition measurements downwind of a section of a full-scale ground sprayer boom tested in a wind tunnel. The measurements include the velocity and turbulence levels generated by the presence (and absence) of the nozzle spray, in addition to nozzle spray deposition patterns. It is envisioned that a description of the turbulent structure of the tractor wake (obtained previously on a subscale tractor) and the nozzle spray, along with flow velocities in the three principal directions, can be used to provide an initial database for velocities and turbulence levels in the vicinity of a typical full-scale ground boom sprayer. The goal of this effort is to use this parameterized wake model to supplement local atmospheric and surface effects around and behind a tractor and spray boom, to better predict the behavior of spray material released from nozzles on a spray boom during actual ground sprayer operation. |
