Droplet deposition of agrochemical spraying: Comparison of results from a random‐walk model and CFD simulations

Abstract: The effectiveness of agricultural spraying processes depends considerably on the ability of the atomized droplets to reach the target site in the desired amount. In this work, two mathematical models to study the trajectories and deposition of atomized droplets are implemented and compared. On the one hand, a computational fluid dynamics (CFD) coupled with discrete phase model (DPM) is implemented to calculate the trajectories of atomized droplets and determine distances at which the droplets are deposited.

“…The third contribution is the paper entitled "Droplet Deposition of Agrochemical Spraying: Comparison of Results from a Random-Walk Model and CFD Simulations" by Carlos E. Renaudo et al [3] The authors used two mathematical models to study the trajectory and the deposition of atomized droplets for use in agricultural spraying processes with the use of CFD models, which takes into account the effects of drag, gravity, buoyancy, and the evaporation of the droplets. The pulverization of the particles is studied using a Lagrangian random-walk (LRW) model implemented in Python, which was compared to CFD results.…”
