Abstract:
The phenomenon of liquid sloshing affects the performance of UAVs used in agricultural spraying. The multi-directional sloshing forces that occur inside the tank can cause the drone to deviate from the specified route and collide with an obstacle. In this study, multiple blade-shaped baffles were used to suppress liquid sloshing in a sprayer drone tank. Numerical simulations using standard k-ε, standard k-ω, SST k-ω turbulence models were performed to evaluate effectiveness of this sloshing suppressor and compare it with a conventional suppressor. In these CFD simulations, the changes in total pressure, fluid velocity at a certain point in the tanks, sloshing force, and water elevation were examined for 50% and 65% filling ratios. It was demonstrated through numerical analyses that both suppressors were very effective in sloshing damping.
