However, certain applications have been reduced to complex simulations that were believed to be impossible to perform. In recent years, new particle-based methods such as smoothed particle hydrodynamics (SPH) and moving particle semi-implicit method have allowed a re-review of these applications, and one clear example of their newly found avail- able execution is the sloshing simulations. This dissertation focuses on the development of a new capability that exploits particle-based simulation advantages, specifically to study sloshing forces on fuel tanks in combines machinery. A theoretical review on the mathematical framework for such methods was performed in order to comprehend the basics behind these simulation softwares, along with a discussion on their advantages and limitations of such methods. Then a sloshing benchmark study with a sensitivity test is conducted to analyze distinct features within the Particleworks software. A high correlation between lab data and simulation data was found, establishing confidence and expertise for the following fuel tank analysis. Images at different time-steps and pressure mapping for three fuel level cases are presented on the tank analysis. Finally, a volume-of-fraction (VoF) method comparison is also provided.TextoengopenAccesshttp://creativecommons.org/licenses/by/4.0CIENCIAS FÍSICO MATEMÁTICAS Y CIENCIAS DE LA TIERRA::FÍSICA::FÍSICA DE FLUÍDOS::LÍQUIDOSScienceTechnologyTesis de maestríaTesis creada con geometría proveniente de John Deere.
