Abstract

Fluid sloshing simulations and tests were performed in a nuclear reactor scheme, especially core meltdown, using the moving particle semi-implicit (MPS) method. The MPS method is a method for analyzing the interactions between incompressible particles. In this method, the fluid is represented by particles, and each particle carries physical information such as position, velocity, pressure, and temperature. The fluid sloshing experiment was carried out using a glass bowl with dimensions of 11 cm x 20 cm x 9 cm and a glass cup with a diameter of 7 cm. The fluids used are water and cooking oil. The results of experiments and simulations with MPS show that the sloshing of the water in the bowl’s middle and outer wall is higher than oil due to the greater water viscosity. The fluid becomes thinner and easier to move as the viscosity increases. In addition, the fluid’s sloshing peak at the bowl’s wall is always greater than in the center of the bowl due to the forces acting on the fluid. The sloshing height from the experiment is greater than the simulation results due to the lifting process of the glass. This study conducted experiments and simulations to determine the fluid dynamics and the effect of fluid differences during fluid sloshing on a representative surface with a core catcher.
