Investigation of Sloshing in a Sprayer Drone Tank with Blade-Shaped Baffles Using Numerical Simulations

<p style="text-align: justify; ">The phenomenon of liquid sloshing affects theperformance of UAVs used in agricultural spraying.The multi-directional sloshing forces that occurinside the tank can cause the drone to deviate fromthe specified route and collide with an obstacle. Inthis study, multiple blade-shaped baffles were usedto suppress liquid sloshing in a sprayer drone tank.Numerical simulations using standard k-ε, standardk-ω, SST k-ω turbulence models were performed toevaluate effectiveness of this sloshing suppressorand compare it with a conventional suppressor. Inthese CFD simulations, the changes in total pressure,fluid velocity at a certain point in the tanks, sloshingforce, and water elevation were examined for 50%and 65% filling ratios. It was demonstrated throughnumerical analyses that both suppressors were veryeffective in sloshing damping.<br>
