Wave Impact Pressure Calculations by Improved SPH Methods

摘要: This paper presents improved Incompressible SPH (ISPH) methods for the prediction of wave impact pressure, more specifically, pressure due to sloshing waves. The first improvement is employment a corrective function enhancing angular momentum conservation. second applies higher-order source term that derived from differentiation less fluctuating and accurate calculation. third proposes new criterion assessment free-surface particles in particle-based enhanced performance ISPH predicting has been shown by simulating 4 cases waves induced sway excitations (Kishev et al., 2006) rotational ones (Delorme 2009).
