Purpose This study aims to evaluate blast loads on and the response of submerged structures. Design/methodology/approach An arbitrary Lagrangian–Eulerian method is developed model fluid–structure interaction (FSI) problems close-in underwater explosions (UNDEX). The “fluid” part provides for structure considers air, water high explosive materials. spatial discretization fluid domain performed with a second-order vertex-based finite volume scheme tangent hyperbola interface capturing...
View Video Presentation: https://doi.org/10.2514/6.2022-0352.vid A numerical model for three-fluid flow including air, water and high explosive (HE) material is extended to fluid-structure interaction (FSI) problems. The aim study the complex interactions between compressible multi-phase flows deformable structures in near field underwater explosions (UNDEX). In this model, ideal equation of state used air. stiffened gas water, Jones-Wilkins-Lee (JWL) HE materials describe detonation...
Purpose – The purpose of this paper is to determine the reason for discrepancy in estimated and observed damage caused by fragmenting charges closed environments. Design/methodology/approach A series carefully conducted physical numerical experiments was conducted. results were analyzed compared. Findings analysis shows that environments, dust plays a far larger role than previously thought, leading much lower pressures damage. Research limitations/implications In light these findings, many...

The treatment of dilute solid (or liquid) phases via Lagrangian particles within mesh-based gas-dynamics hydrodynamic) codes is common in computational fluid dynamics. While these techniques work very well for a large spectrum physical parameters, some cases, notably light or heavy particles, numerical instabilities appear. present paper examines ways mitigating instabilities, and summarizes important implementational issues.
In this work a stabilized large deformation element suitable for real coupled fluid/solid simulations is presented. The uses mixed interpolation (Q1/P0): Standard continuous tri-linear finite (FE) functions the kinematic variables (displacements, velocities and accelerations), constant pressure per (piecewise discontinuous pressures). It well known that type of may show spurious modes (chessboard mode) when used to approximate incompressible fields (i.e. plastic flow, fluids, etc,)....
