Sloshing in vertical cylinders with circular walls: The effect of radial baffles

The behavior of sloshing eigenvalues and eigenfunctions is studied for vertical cylindrical containers that have circular walls constant (possibly infinite) depth. effect breaking the axial symmetry due to presence radial baffles analyzed. It occurs lowest are substantially smaller with going throughout depth; moreover, all simple in this case. On other hand, eigenvalue has multiplicity two absence baffle. shown how these properties affect location maxima minima free surface elevation its nodes.
