# On sloshing modes in a circular tank

@article{Faltinsen2012OnSM, title={On sloshing modes in a circular tank}, author={Odd Magnus Faltinsen and Alexander N. Timokha}, journal={Journal of Fluid Mechanics}, year={2012}, volume={695}, pages={467 - 477} }

Abstract Employing the multipole-type functions given by Faltinsen & Timokha (J. Fluid Mech., vol. 665, 2010, pp. 457–479), we derive a Trefftz-type representation of the velocity potential for the liquid sloshing problem in a two-dimensional circular tank. This representation defines a continuation of the velocity potential into the ‘air’ area confined by the ‘dry’ tank surface. Its usage facilitates an effective approximation of the natural sloshing modes for all tank fillings.
