“…Fig. 11 shows the evolution of the water surface height at the measured point over time, and compares it with the experimental results of Faltinsen [45] and the simulation results of Yan [47] . Comparing the ULPH results with the experimentally measured data, it can be seen that the ULPH measured results are in good agreement with the experimental data.…”

“…The physical variables of the fixed ghost boundary particles are interpolated from the neighboring fluid particles. The free-slip or no-slip boundary conditions can also be applied to this method [24] [36] . For the free-slip solid boundary condition, the viscous force between ghost particles and fluid particles is trivial.…”

In order to solve the fluid-structure interaction problem of Newtonian fluid, a fluid-structure interaction approach is proposed based on Non-ordinary State-based Peridynamics (NOSB-PD) and Updated Lagrangian particle Hydrodynamics (ULPH), to simulate the fluid-structure interaction problem in which large geometric deformation and material failure are considered. In the coupled framework, the NOSB-PD theory is used to describe the deformation and fracture of the solid material structure. ULPH is applied to describe the flow of Newtonian fluids due to its advantages in computational accuracy. The framework effectively utilizes the advantages of NOSB-PD theory for solving discontinuous problems and ULPH theory for solving fluid problems and has good computational stability and robustness. To deal with the interface of fluid structure, a fluid-structure coupling algorithm using pressure as the transmission medium is established. The dynamic model of solid structure and the PD-ULPH fluid-structure interaction model involving large deformation are verified by several numerical validations, which are in good agreement with the analytical solution, the available experimental data and other numerical results, that demonstrates the accuracy and effectiveness of the proposed method in solving the fluid-structure interaction problem. Overall, the fluid-structure interaction model based on ULPH and NOSB-PD established in this paper provides a new idea for the numerical solution of fluid-structure interaction and a promising approach for engineering design and experimental prediction.

“…This is because they may solve fluid and solid dynamic problems by considering some physical aspects that are not considered in potential flow-based models. When it comes to viscous flow, the fluid dynamic problem can be solved by using the finite volume method (FVM) or smoothed particle hydrodynamics (Nakata, Liu & Bomphrey 2015;Sun, Ming & Zhang 2015;Shen et al 2016;Facci, Porfiri & Ubertini 2016;Sun et al 2018;Yan et al 2021;Wang et al 2021;Xiang, Wang & Guedes Soares 2020;Magionesi, Dubbioso & Muscari 2022).

A fluid–solid momentum exchange method for the prediction of hydroelastic responses of flexible water entry problems

The paper presents a Fluid Structure Interaction (FSI) method for hydroelastic water entry. The method assumes that the momentum exchange between the fluid and solid body can be used for the calculation of pressure, deformation and stresses arising during impact. The flexible fluid–structure interactions of flat plates entering water are solved using a computational code that employs the finite volume method to discretise both fluid and solid equations. This provides a better matching of momentum on the fluid–solid interface. The momentum arising in the solid body that emerges after the impact is defined as the momentum exchange, and is shown to increase linearly under the increase of non-dimensional impact speed. The ratio of the maximum pressure arising in an elastic body entering water to that of a rigid body is termed relative pressure and is shown to decrease linearly as a function of momentum exchange. The latter verifies the main hypothesis of this paper, namely that ‘the pressure acting on an elastic body can be predicted using an unsophisticated equation that uses the momentum exchange.’ The deformation and stresses arising in elastic plates entering water are demonstrated to be functions of momentum exchange and can be found using simple equations formulated via parametrisation of data. It is concluded that subject to further validation, the method could be extended for the prediction of hydroelastic response of other sections/bodies entering water.
