Modelling of sloshing in free surface tanks for ShipMo3D ship motion predictions / by Kevin McTaggart: D68-7/084-2011E-PDF
Ship roll motions in waves can be significantly influenced by the presence of tanks containing liquids, which experience sloshing. Sloshing effects must be considered when transporting liquid cargo; however, sloshing can also be used to advantage. Many vessels have specially designed flume tanks to provide passive roll stabilization. This report describes the implementation of a model of fluid sloshing in tanks for the ShipMo3D ship motion library. The sloshing model is based on potential flow, giving a solution that is computationally efficient and robust. The potential flow model includes a simplified treatment of flow damping arising from viscous effects. The tank sloshing model has been implemented for computations in both the frequency and time domains. Example computations for a generic frigate demonstrate the reduction of roll motions using a flume tank.
