| Outline of Final Research Achievements |
This study aimed at proposing a coupled FSI (Fluid-Structure Interaction) solver for hydroelastic slamming with two major aims of 1) further development of a particle-based multiphase computational code for more precise modeling of entrapped air dynamics in water slamming, 2) accurate coupling of a refined multiphase flow model with a non-linear elastic structure model for precise modeling of hydroelsatic slamming. As for the first aim to avoid use of conventional density averaging schemes, a new scheme, namely, Optimized Particle Shifting (OPS), was proposed and then a multiphase algorithm comprising of this scheme was developed. As for the second aim, significant efforts were devoted to development of fully-Lagrangian meshfree FSI solvers that can precisely model the related non-linear hydroelastic slamming problems. Several fully-Lagrangian meshfree solvers with different coupling schemes were developed with the results being published in four journal papers.
