Abstract
The sloshing phenomena in a spray mixture tank is evaluated in a numerical analysis with results of some computer simulations of fluid dynamics (CFD). The computation of the effects of sloshing due to the braking deceleration of an agricultural vehicle is carried out in three levels of tank filling (25%, 50% and 75%) and without mechanical agitation, in order to define the most critical conditions for the structural dimensioning of the tank. It is evaluated pressure time histories against tank wall using a multiphase transient model (water and air-ideal gas) with a free surface flow in a homogenous model. Thus, we could verify the wave’s performance of sloshing, and the condition of higher tank filling volume (75%) was the one that generated the highest-pressure values on the tank wall. The tank level of 50%, achieved higher-pressure oscillation frequency.
