| Summary: | Liquid in an arbitrary shaped container under external excitations, results in surface and bulk turbulence. The nature of such turbulence is quite complex due to several effects such as sloshing,pressure gradient etc. Amongst these, sloshing makes the liquid container more vulnerable to structural damages. Depending on the type of disturbance and container shape, the fiee liquid surface may experience different types of motion including simple planar, non-planar, rotational, irregular beating,symmetric,asymmetric, quasi-periodic and chaotic. However, the amplitude of slosh depends on the amplitude and frequency of the tank motion, liquid-fill depth, liquid properties and tank geometry. The resonance in the case of horizontal excitation occurs when the external forcing fiequency is close to the natural frequency of the liquid. Hence liquid sloshing is a practical problem with regard to the safety of
transportation systems, such as oil tankers on highways, liquid tank cars on railroads, oceangoing vessels with liquid cargo, propellant tank used in satellites and other spacecraft vehicles, and several others |
