摘要：
A series of sloshing model tests for various viscous liquids were carried out and the effects of liquid viscosity on sloshing are investigated quantitatively in this paper. The experimental results show that the liquid viscosity has an important effect on sloshing pressure, which is the mean value of those peak pressures from several consecutive periods. Energy dissipation due to viscous friction leads to reduction of sloshing pressure and the dissipation effect is more remarkable, especially when liquid viscosity becomes higher. As a result of viscous damping effect, the rising time of impact pressure is longer in higher viscosity liquid.
