Modelling of sloshing in free surface tanks for ShipMo3D ship motion predictions [electronic resource] / by Kevin McTaggart [Ottawa] : Defence Research and Development Canada, c2012. x, 46 p. : tables, figures. External client report ; 2011-084 "January 2012." Includes bibliographical references. 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. gccst Technical reports Frequency domain Ship motions Defence R&D Canada.
