Inflow/outflow with Dirichlet boundary conditions for pressure in ISPH
Journal of Computational Physics, 2016In the present work we propose a new algorithm for open boundary treatment in ISPH. In the literature a few models for open boundary conditions are available, but most of them are applied to weakly compressible SPH (WCSPH) only. In our method the inflow/outflow is driven by true Dirichlet boundary conditions of the projected pressure field.

Comparative Analysis of the SPH and ISPH Methods
2009Free 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 ...

Improved Method of Splash Fluid Simulation Based on ISPH
Proceedings of the 2nd International Conference on Computer Science and Software Engineering, 2019Flowing 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 ...

A Comparative Study on Violent Sloshing with Complex Baffles Using the ISPH Method [PDF]
Applied Sciences (Switzerland), 2018 The Smoothed Particle Hydrodynamics (SPH) method has become one of the most promising methods for violent wave impact simulations. In this paper, the incompressible SPH (ISPH) method will be used to simulate liquid sloshing in a 2D tank with complex baffles.

Wave Impact Simulations by an Improved ISPH Model
Journal of Waterway, Port, Coastal, and Ocean Engineering, 2014AbstractThis paper presents an improved incompressible smoothed particle hydrodynamics (ISPH) method for wave impact applications. In most conventional ISPH techniques the source term of the pressure Poisson equation (PPE) is usually treated by either a density invariant or a velocity divergence-free formulation.

ISPH modeling of Rayleigh–Taylor instability [PDF]
, 2011 This paper presents a Smoothed Particle Hydrodynamics (SPH) solution to a Rayleigh-Taylor Instability (RTI) problem in an incompressible viscous two-phase immiscible fluid with an interfacial tension. The evolution of the fluid-fluid interface is numerically investigated for four different density ratios.

Reduktive Dehydroxylierung von Allylalkoholen durch IspH‐Protein
Angewandte Chemie, 2010AbstractDie Biosynthese von Naturstoffen ist eine Fundgrube für ungewöhnliche Reaktionsmechanismen. Neue strukturbiologische und mechanistische Untersuchungen machen verständlich, wie Allylalkohole im Rahmen der Terpen‐Biosynthese durch das IspH‐Protein reduktiv dehydroxyliert werden.

An ISPH model for flow-like landslides and interaction with structures
Journal of Hydrodynamics, 2017Abstract An incompressible smoothed particle hydrodynamics (ISPH) model has been developed to investigate the flow-like landslide phenomena The landslide mass is idealized as rigid and perfectly-plastic material with a constant density. Unlike the widely-used explicit smoothed particle hydrodynamics (SPH) models for landslides, the Chorin's ...

ISPH simulation of droplet spreading at different Eotvos numbers
AIP Conference Proceedings, 2013In this study, a method for modeling incompressible, immiscible three phase fluid flows in the context of incompressible smoothed particle hydrodynamics (ISPH) in two dimensions has been proposed. Continuum surface force model is employed while physical surface tension coefficients are expressed as the sum of phase specific surface tension coefficients.
