N2 - In the present paper, two-dimensional violent sloshing flows are simulated by a constraint interpolation profile method combined unified procedure (CCUP) and smoothed particle hydrodynamics (SPH) method. The present CCUP scheme is based on finite difference method and constrained interpolation profile (CIP) method. Freesurface flows are considered as multi-phase problems with air and water phases. The tangent of hyperbola for interface capturing (THINC) scheme is applied to trace free-surface profile. The SPH method based on Lagrangian formulation is also applied in this study to simulate violent fluid deformations due to sloshing. Numerical simulations are carried out for partially filled 2-D tanks under harmonic sway and roll motions with various water depths and frequencies, and the results are compared for both methods.
