Abstract
Moiseev's procedure (1958) is used to derive a combined numerical and analytical method for sloshing in a general two-dimensional tank with vertical sides at the mean waterline. It is shown that the latter rest riction follows from conservation of fluid mass. A low-order panel met hod based on Green's second identity is used as part of the solution. The method is verified by comparison with the analytical solution by F altinsen (1974) for a rectangular tank shape. It is demonstrated that more than 100 elements may be needed to describe the free surface in t he panel method.
