One of the critical points in the numerical simulation of liquid sloshing is the assessment of the hydrodynamic impact pressure. Unnatural violently-oscillating time histories of the impulsive pressure, caused by unstable or even non-converging numerical computation, are generally obtained by the available numerical methods. The unstable nature of the impulsive pressure computation is investigated in this paper. Also, a new numerical technique for accurate and stable assessment of the impact pressure is proposed. The comparisons of the computed results with the experimental ones confirmed the accuracy of the proposed technique. The improvements achieved over the existing approaches are also shown.[graph]
