Flow kinematics and impact pressure of a partially filled liquid sloshing flow produced by the periodic motion of a rectangular tank were studied experimentally. The main focus was on quantifying the flow velocities and impact pressures induced by the flow. The tank was filled with water at a 30% filling ratio and oscillated at a resonant frequency to generate the violent sloshing flow. The flow velocities were measured using the bubble image velocimetry technique. A total of 15 pressure sensors were mounted on the top wall and a side wall to measure the impact pressures. The local kinetic energy obtained by the measured local velocities was used to correlate with the corresponding pressures and determine the impact coefficient. It was observed that the impact coefficients differed by almost one order of magnitude between the side wall impact and the top wall impact, mainly due to the large difference between the local velocities.
