Tanmoy Konar, Anupam Das
Abstract
Sloshing of liquid in a partially filled container, which has a significant bearing on the dynamic stability of the container and its supporting structure, is a multi-disciplinary engineering topic. Numerical methods are often used to model the phenomenon of liquid sloshing, especially for handling large amplitude sloshing, and sloshing in tanks with flexible walls or complex geometry or submerged objects. Several mesh-based and mesh-less numerical approaches are used to model liquid sloshing depending on the required degree of accuracy, the possibility of having a stable solution, the extent of nonlinearity associated with the problem, etc. This is still a developing field of research, and rigorous efforts are devoted to developing new numerical methods and improving the existing ones. This necessitates the present work, through which a state-of-the-art review of the existing numerical methods of modelling liquid sloshing is presented while highlighting the assumptions, limitations, and applicability of each method. Significant recent works in this field are also presented in a summarised form. The scope of future developments is also identified.
