“…The viscosity term and the source item of momentum conservation equation are calculated explicitly. Moreover, MPS is a fully Lagrange method by time advancing, and every fluid particle can be tracked easily [7,8]. This study may give useful suggestions on controlling the mass transfer accurately during the pouring process.…”

“…The pouring process is simulated numerically by a meshless particle method, the moving particle semi-implicit (MPS) method [2]. The MPS method is a kind of mesh-free method, which has advantages over mesh based methods on problems with large deformation [3][4][5][6][7], such as the free surface motion of shattering or merging [8]. In this method, the Navier-Stockes equations are discretized and reformed into a Poisson equation of pressure which is solved implicitly.…”

Liquid flows in a particular sequence when it is poured out from an open-top receptacle. Since the sequence is hard to catch by experiment, a numerical simulation was performed in this pouring process with the moving particle semi-implicit (MPS) method. A modified solid-liquid boundary condition was verified and employed with a new definition of static liquid layers. The whole system was discretized by a set of particles and the liquid particles were marked and tracked in the pouring process. The flowing sequence of the liquid can be calculated by restoring the liquid particles back to their initial positions before it is poured. The mass transfer property is found to depend on the position of the rotation axis and the rotation speed, as well as the viscosity of the liquid. The mechanism of the flowing sequence results from a temporal vortex and its motion during the process. The character vortex is generated by the rotation of the container. The results reveal a principle for a versatile pouring process and may contribute to the applications in flowing control in many fields. meshless method, particle method, flowing sequence, pouring liquid, flow control

“…As meshes are not required, the MPS method has been extended to many applications, including ocean engineering (Shibata and Koshizuka 2007), bubble rising (Shakibaeinia and Jin 2012), nuclear engineering (Koshizuka, Ikeda, and Oka 1999), chemical engineering (Sun et al 2014), and mechanical engineering (Sun, Xi, and Chen 2009). Boundary conditions play an important part in such engineering applications.…”

The boundary conditions represented by polygons in moving particle semi-implicit (MPS) method (Koshizuka and Oka, Nuclear Science and Engineering, 1996) have been widely used in the industry simulations since it can simply simulate complex geometry with high efficiency. However, the inaccurate particle number density near non-planar wall boundaries dramatically affects the accuracy of simulations. In this paper, we propose an initial boundary particle arrangement technique coupled with the wall weight function method (Zhang et al. Transaction of JSCES, 2015) to improve the particle number density near slopes and curved surfaces with boundary conditions represented by polygons in three dimensions. Two uniform grids are utilized in the proposed technique. The grid points in the first uniform grid are used to construct boundary particles, and the second uniform grid stores the same information as in the work by Zhang et al. The wall weight functions of the grid points in the second uniform grid are calculated by newly constructed boundary particles. The wall weight functions of the fluid particles are interpolated from the values stored on the grid points in the second uniform grid. Because boundary particles are located on the polygons, complex geometries can be accurately represented. The proposed method can dramatically improve the particle number density and maintain the high efficiency. The performance of the previously proposed wall weight function (Zhang et al.) with the boundary particle arrangement technique is verified in comparison with the wall weight function without boundary particle arrangement by investigating two example geometries. The simulations of a water tank with a wedge and a complex geometry show the general applicability of the boundary particle arrangement technique to complex geometries and demonstrate its improvement of the wall weight function near the slopes and curved surfaces.
