“…The first class of studies is dedicated to improving border conditions, which means proposing other solutions for representing and calculating the fluid's free surface [89][90][91][92] . In the category of fluid behaviour, the SPH is used to simulate incompressible [93] and compressible fluids [94] , besides that the method offers the capability of calculating multi-fluid interactions [95,96] or fluid-structure interaction [97] . Another highly interesting application for this methodology in the computational graphics field is the possibility to predict the fluid's movement and final form [98,99] .…”

The current work is intended to give an overview of issues related to the numerical simulation of adhesive spreading for liquid to semi-liquid adhesives. The advantages and limitations are presented in order to guide the choice of the suitable approach depending on the case under consideration. It is shown that methods are of two categories, whether they are grid-based or meshless. In the first, the movement of the matter is directly dependent on the mesh size and distribution. Contrariwise, in the meshfree methods, the particles are free to move and each carries its properties. Besides, cases of application are presented to provide a database for calculating adhesive spreading with the particulate SPH method. It is shown that it is possible to use simple behaviour laws to win this case.

“…35,36) Many researcher try to improve the accuracy and robustness of SPH method, various techniques for stabilized calculation have been proposed. [37][38][39] In this study, a simple and relatively classical solution method was adopted as the first step of model development. The artificial viscosity proposed by Monaghan 40,41) has been classically used due to its simplicity.…”

A new simulation model for the analysis of solid to liquid phase transition behaviors inside the blast furnace was developed in this study. The solid state is treated by ADEM (Advanced Distinct Element Method) and the liquid state is treated by SPH (Smoothed particle Hydrodynamics). The intermediate state is treated by overlapped calculation of both ADEM and SPH. Numerical examinations for the analysis of several phenomena such as dam brake flow, droplet deformation due to the contact angle and phase transition were performed. The validity of the proposed model was confirmed by comparison with the experimental results of the motion of the leading edge in collapse of a water column in the dam break test. The phase transition behavior of ore was observed experimentally using horizontal furnace. The deformation started at about 1 200°C from the upper corner of sample pellet became round, and melted down to the whole with slight contraction. A similar behavior is also can be seen in the simulation by appropriately setting the relationship between the temperature and the joint spring coefficient. These results are indicated that the developed model has possibility to clarify the burdens behavior including the phase transition inside the blast furnace.

“…The natural period of the prismatic tank was estimated using Equations (21) and (22), which were derived by Faltinsen and Timokha [55], where ω n is the natural frequency of the i-mode for a rectangular tank, d represents the water height, and l represents the length of the free surface in the direction of tank movement. For a prismatic tank with a chamfered bottom, a correction factor was introduced in Equation (22), where δ 1 and δ 2 are the horizontal and vertical dimensions of the chamfer, respectively.…”

This study aimed to validate the single-phase and two-phase smoothed particle hydrodynamics (SPH) on sloshing in a tank. There have been many studies on sloshing in tanks based on meshless particle methods, but few researchers have used a large number of particles because there is a limitation on the total number of particles when using only CPUs. Additionally, few studies have investigated the influence of air phase on tank sloshing based on two-phase SPH. In this study, a dedicated sloshing experiment was conducted at the National Research Institute of Fishing Engineering using a prismatic tank with a four-degrees-of-freedom forced oscillation machine. Three pressure gauges were used to measure local pressure near the corners of the tank. The sloshing experiment was repeated for two different filling ratios, amplitudes, and frequencies of external oscillation. Next, a GPU-accelerated three-dimensional SPH simulation of sloshing was performed using the same conditions as the experiment with a large number of particles. Lastly, two-dimensional sloshing simulations based on single-phase and two-phase SPH were carried out to determine the importance of the air phase in terms of tank sloshing. Based on systematic comparisons of the single-phase SPH, two-phase SPH, and experimental results, this paper presents a detailed discussion of the role of air-phase in terms of sloshing. The currently achievable accuracy when using SPH is demonstrated together with a few sensitivity analyses of SPH parameters.
