A new two-step projection method in an ISPH model for free surface flow computations

Coastal Engineering, 2017
Abstract In this study, we propose a new two-step projection method in connection with an ISPH model. Compared to the traditional ISPH model that uses the future time step pressure to calculate the intermediate velocity, in the present study the pressure at both current time step and future time step is employed.

Improved Method of Splash Fluid Simulation Based on ISPH

Proceedings of the 2nd International Conference on Computer Science and Software Engineering, 2019
Flowing and splashing are the most common fluid phenomena in the nature. Fluid simulation has already been widely used in film, game and other industrial numerical field. Furthermore, both the theoretical study [1] and the practical experience [2] show that simulations of flexible fluid splashes and other dynamic scenarios are more accurate and ...

Comparative Analysis of the SPH and ISPH Methods

2009
Free surface problems in fluid mechanics are of a great applied importance, and that’s why they rouse many researchers to excitement. Numerical simulations of such problems, using the so-called meshless methods, become more and more popular today. One of the subsets of these methods is the class of meshless particle methods, which don’t use any mesh ...

A multiphase ISPH method for simulation of droplet coalescence and electro-coalescence

International Journal of Multiphase Flow, 2018
Abstract In this paper, a numerical algorithm is introduced for simulation of droplet coalescence and electro-coalescence within the framework of the Smoothed Particle Hydrodynamics (SPH) method. The algorithm is developed based on the film drainage model which is used for simulation of coalescence in mesh-dependent methods.

Water entry of decelerating spheres simulations using improved ISPH method

Journal of Hydrodynamics, 2018
In this paper, we simulated the vertical impact of spheres on a water surface using three-dimensional incompressible smoothed particle hydrodynamics (3-D ISPH) method. The sphere motion is taken to be a rigid body motion and it is modeled by ISPH method. The governing equations are discretized and solved numerically using ISPH method.
