Abstract Sloshing describes liquids motion in the semi-filled tanks, and exerts dynamic loading on its walls. This effect is of great importance in a number of dynamic systems e.g. aerospace vehicles, road tankers, liquefied natural gas carriers, elevated water towers and petroleum cylindrical tanks. Pressures insert impacts which are important for structural strength evaluation and its co...

In this paper, we propose an interactive method based on Smoothed Particle Hydrodynamics (SPH) to simulate blood as a fluid with free surfaces. While SPH was originally designed to simulate astronomical objects, we gear the method towards fluid simulation by deriving the force density fields directly from the Navier-Stokes equation and by adding a term to model surface tension effects. In contr...

[PySPH] is a Python-based open source parallel framework for Smoothed Particle Hydrodynamics (SPH) simulations. It is distributed under a BSD license. The performance critical parts are implemented in [Cython]. The framework provides a load balanced, parallel execution of solvers. It is designed to be easy to extend. In this paper we describe the architecture of PySPH and how it can be used. At...

We have performed Smoothed Particle Hydrodynamics (SPH) simulations to study the time evolution of one and two protoplanets embedded in a protoplanetary accretion disc. We investigate accretion and migration rates of a single protoplanet depending on several parameters of the protoplanetary disc, mainly viscosity and scale height. Additionally, we consider the influence of a second protoplanet ...

Abstract In Smoothed Particle Hydrodynamics (SPH) methods for fluid flow, incompressibility may be imposed by a projection method with an artificial homogeneous Neumann boundary condition for the pressure Poisson equation. This is often inconsistent with physical conditions at solid walls and inflow and outflow boundaries. For this reason open-boundary flows have rarely been computed using SPH....

A hypoplastic constitutive model is implemented in a Smoothed Particle Hydrodynamics (SPH) code for the first time. An improved wall boundary treatment is presented for better performance. The proposed approach is first validated by comparing the numerical results with the analytical solutions for oedometer test. Two more problems involving large deformation, i.e. the collapse of sand between t...

The chemical and photometric evolution of star forming disk galaxies is investigated. Numerical simulations of the complex gasdynamical flows are based on our own coding of the Chemo Dynamical Smoothed Particle Hydrodynamical (CD SPH) approach, which incorporates the effects of star formation. As a first application, the model is used to describe the chemical and photometric evolution of a disk...

Recent calculations with a two-fluid smoothed particle hydrodynamics (SPH) code of the collapse of a magnetized dense core have found little evidence for fragmentation. These calculations have been interpreted as implying that magnetic braking by magnetic tension forces is sufficient to inhibit fragmentation, contrary to a suggestion by Boss that magnetic fields might encourage fragmentation. H...

The control of dense crowd is a time-consuming and challenging task. There are always conflicts between detailed movements and the control of large-scale crowd. To solve this problem, we suggest the smoothed particle hydrodynamics (SPH) technique to express continuous flow with two authorable interfaces. To reflect the connectivity that occurs in a crowd, we use an authorable sociogram model. A...
