矩形貯槽のスロッシング現象とプラスチックフィルターを用いた抑制方法

Abstract

The water tank damages caused by the sloshing were reported in case of earthquake. In this study, the experiment to investigate the sloshing behavior of different dimensional aspect ratio of rectangular tank under the different excitation angle has been performed. In addition, the special size tank, such as the aspect ratio is close to 1:1, has been examined in detail. And, based on the results of these experiments, sloshing control methods using plastic filter has developed. For example, filter installation position, depth, length, and so on. Finally, we obtained the effective filter installation position and area for the tank wall.
