A study on the sloshing effect on the motion of 2d boxes in regular waves
In this paper, we present a fundamental study on the sloshing effect for the sway motion of two boxes in two dimensions. First, we carry out experiments for two boxes of the same size and also different size in regular waves with different filling ratios, where the boxes are firmly connected each other. The sway motion is measured by a non-contact video camera. The measured motion is compared with numerical results obtained by using a computer program constructed based on the single-dominant multi-modal method. Good agreements are in general found, but clear discrepancies can also be observed at some incident wave frequencies. The friction on the tank rail and the locally resonated fluid motion between two boxes are regarded as main error sources. Therefore, it is necessary to clarify these error sources to predict more accurately.
