The aim of this project is to gain basic knowledge about the influence of the pump tower on sloshing and sloshing-induced loads on tank walls, and the tower itself, by means of experiments. The flow velocities, the shape of the free surface, the sloshing-induced pressures on the tank walls and the tower loads (fluid dynamic forces and moments) are examined. An octagonal test tank, which enables the installation of a pump tower, the measurement of pressures on the tank walls and loads on the pump tower, is used for the investigations. In addition, the design of the tank also enables the usage of a gas of higher density compared to air.
Selected conditions are chosen to determine the effect of a different density ratio on the measured data. Miniature pressure sensors are inserted flush into the tank walls to measure the pressures. A method using a multi-component sensor is being developed to realize the measurement of the loads on the pump tower. The behavior of the free surface is evaluated with the help of high-speed video recordings and the measurement of flow velocities in the tank is carried out with PIV. Several test series with different tank movements and impact scenarios are used to analyze all measurement data.
