Liquid Sloshing in Containers with Flexibility : Tuning container flexibility for sloshing control

Sloshing is the low frequency oscillation of the free surface of a liquid in a partially filled container. If not controlled effectively, sloshing may cause excessive dynamic loads which may lead to structural failure (in case of storage containers) or loss of dynamic stability (in case of transport vehicles). Hence, study and control of liquid sloshing is a well justified topic in engineering and science. Container flexibility causes moving boundaries which further complicate the treatment of this already challenging problem. On the other hand, container flexibility may be treated as a design parameter to gain benefit in controlling the free surface oscillations. Although numerous studies have been reported in the literature, attempts to control sloshing have been relatively limited. This book details numerical predictions using standard finite elements software (ANSYS) for the simulation of liquid sloshing in a flexible container.
