Flexible slender body fluid interaction: Vector-based discrete element method with Eulerian smoothed particle hydrodynamics

Three‐dimensional weakly compressible moving particle simulation coupled with geometrically nonlinear shell for hydro‐elastic free‐surface flows

“…Here, we extended the formulation proposed by Jandaghian and Shakibaeinia, 73 see Equation (21), to consider the polygonal walls. The divergence of the velocity associated with the virtual neighboring particles V i (see Figure 2), considering the free-slip boundary condition, is obtained by:…”

“…The mesh‐free particle‐based (Lagrangian) methods, such as smoothed particle hydrodynamics (SPH) 1,2 and moving particle semi‐implicit/simulation (MPS), 3 are very effective to model violent FSI free‐surface flows with large interfacial deformation and fragmentations 4,5 . These methods have been widely developed in the context of hydroelasticity 6,7 and many others as reviewed by Gotoh et al, 8 with some focused on parallel computing in graphics processing units, 9,10 and applied to solve related problems such as sloshing, 11,12 slamming, 13 dam breaking, 14 tsunami, 15,16 structure failures, 17,18,19 composite structures, 20 and biomedical engineering 21 …”

In that case, some authors adopted multiresolution techniques, 22,23,24,25,26,27 in which high resolution is used only near the structures or local critical areas.…”

Analysis and FPGA Realization of a Novel 5D Hyperchaotic Four‐Wing Memristive System, Active Control Synchronization, and Secure Communication Application

“…Nonlinear science is a new interdisciplinary subject to study the universality of nonlinear phenomena, which runs through almost every subject of meteorology [1,2], mathematics [3][4][5][6], uid mechanics [7,8], complex network [9][10][11][12], electronics [13][14][15], and social science [16,17]. Chaos is one of the most important achievements of nonlinear science.…”

Numerical modeling of fluid-structure interaction (FSI): time-consistent pressure computation, rigid bodies contact and coupled particle-mesh methods.

“…The mesh-free particle-based (Lagrangian) methods, such as the smoothed particle hydrodynamics (SPH) (Gingold & Monaghan, 1977;Lucy, 1977) and the moving particle semi-implicit (MPS) (Koshizuka & Oka, 1996), are very effective to model violent freesurface flows with large interfacial deformation and fragmentations. These methods have been widely applied to solve FSI problems (Chikazawa et al, 2001) (Antoci et al, 2007) (Rafiee & Thiagarajan, 2009) (Amini et al, 2011) (Amaro Junior & Cheng, 2013) (Hwang et al, 2016) (Falahaty et al, 2018) (Khayyer et al, 2018) (Nasar et al, 2019) (Sun et al, 2019 (Wang et al, 2019) (Zhan et al, 2019) (Liu et al, 2020).…”
