Fluid-Structure Interaction Analysis on Membrane Behavior of a Microfluidic Passive Valve

“…FSI analysis of the two-way coupling method transfers the pressure calculated by fluid domain to the solid domain, and the nodal displacement calculated by the solid domain is returned to the fluid domain to update the flow field [ 25 ]. This coupling method needs to consider every field, i.e., fields that including the fluid flow, structural deformations, and moving mesh need to be considered during the coupling process, as shown in Figure 3 .…”

Investigation of the Sloshing Behavior Due to Seismic Excitations Considering Two-Way Coupling of the Fluid and the Structure

“…u, and u are the acceleration, velocity, and displacement vectors, respectively. As can be seen in the equation, damping is included in the numerical calculations knowing that damping is not very effective for inertia-driven problems containing continuous interaction [26]. Rayleigh damping proportional to a linear combination of mass and stiffness was used:…”

“…Various numerical models to couple fluid-structure interaction problems, such as MPS-FEM coupling [21] or immersed boundary methods combined with volume of fluid or level-set approaches [22][23][24], have been proposed in the literature [25]. In the present numerical model, smoothed particle hydrodynamics was coupled with the finite element method, and the coupling was satisfied with contact mechanics [26,27]. SPH, a Lagrangian and mesh-free method, was originally developed to simulate astrophysical problems [28,29].…”

Hydro-elastic analysis of standing submerged structures under seismic excitations with SPH-FEM approach

“…Nowadays, researchers propose new methods or combined methods (Demir et al 2019;Dinçer et al 2019;Fernández-Méndez, Bonet, and Huerta 2005) already in use for better simulations. Some researchers use mesh-based methods (Cho and Lee 2004;Ghalandari et al 2019) to take the advantage of robustness.…”
