Excitation forces induce fluid sloshing that finally leads to internal structural damage and fluid impact noise. Therefore, to minimizing sloshing effect, many researchers have been studying about it. However, most of researchers are not interested in air behavior on a free surface. If there are baffles which block the air in a tank, sloshing decrease but a tank is pressurized by air. The purpose of this paper is to examine air behavior over sloshing in a rectangular tank. We performed a numerical study using CFX, and k-ε model was used for it. To excite sloshing in the tank, we used a function about Asin(2πft) where A is amplitude, f is frequency and t is time. To verify the reliability of the results of analysis, the result is compared with the experimental results of the previous study. Also we analyzed air behavior and sloshing in a tank with baffles.
