EVALUATION OF SLOSHING IMPACT PRESSURE USING THREE-DIMENSIONAL NUMERICAL WAVE TANK “CADMAS-SURF/3D”

Abstract

 In this study, a three-dimensional numerical wave tank “CADMAS-SURF/3D” with VOF method was improved for evaluating sloshing behavior and hydrodynamic pressure inside the reservoir generated by earthquake. Model experiments and numerical simulations were conducted in order to examine the validity of the numerical model.

 The experimental results revealed that the magnitude and vertical distribution of the hydrodynamic pressure are different depending on the relationship between the natural frequency of the reservoir and the earthquake frequency. The numerical model proposed in this study was shown to be able to reproduce the laboratory experiments appropriately.
