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

Autor: Abouzied Nasar, Peter Stansby, Alistair Revell, Benedict D. Rogers

Publikováno v: Computers & Fluids. 179:563-578

In this paper Eulerian weakly compressible SPH (EWCSPH) is coupled to the Vector-based discrete element model (V-model) to produce a robust mesh-less SPH-V model for fluid-structure interaction (FSI) applications including thin highly flexible bodies

Towards pseudo-spectral incompressible smoothed particle hydrodynamics (ISPH)

Autor: Georgios Fourtakas, Benedict D. Rogers, Abouzied Nasar

Publikováno v: Computer Physics Communications. 266:108028

In this paper a pseudo-spectral incompressible smoothed particle hydrodynamics (FFT-ISPH) solver is presented. While the solution of the linear system arising from the pressure Poisson equation in physical space using iterative solvers in incompressi

High order difference schemes using the Local Anisotropic Basis Function Method

Autor: Steven Lind, Abouzied Nasar, Jack King

Publikováno v: King, J R C, Lind, S J & Nasar, A 2020, ' High order difference schemes using the Local Anisotropic Basis Function Method ', Journal of Computational Physics, pp. 109549 . https://doi.org/10.1016/j.jcp.2020.109549

Mesh-free methods have significant potential for simulations in complex geometries, as the time consuming process of mesh-generation is avoided. Smoothed Particle Hydrodynamics (SPH) is the most widely used mesh-free method, but suffers from a lack o
