SBFEM with multimodal method are used to laterally-excited sloshing in cylindrical tanks with multi baffles.
A new coordinate system and solving process for SBFEM with axisymmetric geometry are presented.
Floating circular, wall-mounted ring and floating ring baffles or with inclination have been investigated.
Solution by the proposed method has higher accuracy and efficient than that of the other methods.
Effects of liquid fill level, baffled arrangement and length upon sloshing characteristics are investigated.
