In this paper, we propose a novel GPU-friendly algorithm for the Smoothed Particle Hydrodynamics (SPH) simulation for weakly compressible fluids. The major goal of our algorithm is to implement a GPU-based SPH simulation that can simulate and render a large number of particles at interactive speed. Additionally, our algorithm exhibits the following three features. Firstly, our algorithm support...

Although Eulerian approaches are standard in computational acoustics, they are less effective for certain classes of problems like bubble acoustics and combustion noise. A different approach for solving acoustic problems is to compute with individual particles following particle motion. In this paper, a Lagrangian approach to model sound propagation in moving fluid is presented and implemented ...

A new kernel function is developed to approximate the third order derivative by mean of Smoothed Particle Hydrodynamics (SPH) method. It has advantage be efficiently used with gridded data and random distributions. Due discrepancy particles in former distribution, we extended use CSPM method for approximation derivatives. Our provides three accurate numerical schemes, conjunction trapezoidal ru...

With wide applications, the smoothed particle hydrodynamics method (abbreviated as SPH) has become an important numerical tool for solving complex flows, in particular those with a rapidly moving free surface. For such problems, the incompressible Smoothed Particle Hydrodynamics (ISPH) has been shown to yield better and more stable pressure time histories than the traditional SPH by many papers...

The penetration of projectiles into targets has a broad background in engineering. In this work, numerical simulations the projectile-target problem are conducted using Finite Element Method (FEM), Smoothed Particle Hydrodynamics (SPH) and Element–Smoothed Adaptive Coupling (FE-SPH ACM) based on LS-DYNA software package. First, experiments aluminum ceramic simulated. experimental simulation res...

Coastal protections, such as dykes, seawalls, breakwaters and natural beaches can often be considered porous structures.
