The sloshing problem has been studied in recent decades, as it causes damage to the container structure, caused by hydrodynamic loads. In our work, we show that it is possible to mitigate the action of the fluid on the structure. First, we applied Smoothed Particle Hydrodynamics (SPH) to perform numerical simulations involving the sloshing effect in tanks used to transport Liquefied Petroleum Gas similar to the physical experiments found in the literature. Then, we added (on the container floor) to our numerical model attenuation devices in order to reduce the sloshing effect. Two types of sloshing suppressors were used, where two different heights are assigned and tested. In addition, we changed the deflector's morphology, leaving it in the shape of an arrow pointing upwards. The results have shown that the baffles can be efficient mechanisms for the suppression of sloshing and that there is a strongly relationship between the height of the baffles and the level of fluid in relation to the tank.

O presente estudo apresenta uma comparação entre a aplicação de um modelo Lagrangiano sem malhas e de um modelo Euleriano, com emprego de malhas, para o estudo da propagação de ondas em regiões costeiras. O modelo numérico euleriano se fundamenta nas equações não-lineares de ondas do tipo Boussinesq e o modelo numérico Lagrangiano sem malhas emprega o método Smoothed Particle Hydrodynamics. Os resultados das simulações numéricas mostraram concordância dos modelos no comportamento da superfície livre. A maior discrepância ocorreu na região de arrebentação da onda, durante a quebra, e no run-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
