Boundary condition enforcing methods for smoothed particle hydrodynamics
نویسندگان
چکیده
A Boundary Condition Enforcing (BCE) marker approach is implemented in [9] to capture the fluid interaction with solid boundaries. BCE markers are treated there as fluid markers attached to solid surface. The velocity of each BCE marker is the same as the local solid velocity, while the pressure is obtained by projecting the fluid local pressure in the boundary normal direction. Alternatively, an approach was proposed recently [1] to improve the boundary accuracy by modifying the BCE velocity and pressure to reproduce the wall velocity and force balance at the boundary. These two approaches are compared herein.

Investigating the Third Order Solitary Wave Generation Accuracy using Incompressible Smoothed Particle Hydrodynamics
This paper examines the generation and propagation of a Third order solitary water wave along the channel. First the Incompressible Smoothed Particle Hydrodynamics (ISPH) numerical method is described and the boundary condition handling method is presented. The numerical model is then used to simulate solitary wave propagation along the fixed depth channel. The numerical results are compared wi...
متن کاملNumerical Simulation of Squeezed Flow of a Viscoplastic Material by a Three-step Smoothed Particle Hydrodynamics Method
In the current work, the mesh free Smoothed Particle Hydrodynamics (SPH) method, was employed to numerically investigate the transient flow of a viscoplastic material. Using this method, large deformation of the sample and its free surface boundary were captured without the cumbersome process of the grid generation. This three-step SPH scheme employs an explicit predictor-corrector technique an...

A meshless numerical technique is proposed for solving the generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system with electromagnetic fields. The employed meshless technique is based on a generalized smoothed particle hydrodynamics (SPH) approach. The spatial direction has been discretized with the generalized SPH technique. Thus, we obtain a system of ordinary...

This work outlines a unified multi-threaded, multi-scale High Performance Computing (HPC) approach for the direct numerical simulation of Fluid-Solid Interaction (FSI) problems. The simulation algorithm relies on the extended Smoothed Particle Hydrodynamics (XSPH) method, which approaches the fluid flow in a Lagrangian framework consistent with the Lagrangian tracking of the solid phase.
