“…To illustrate the method, we consider a five-point difference scheme, e.g. for equation (2.2), given by The validation of the code in the sense of the particle collisions was done in comparison with the recent experiment of Zhang et al [5]. Following the experiment [5], we considered the collapse of a stack of 33 aluminium cylinders owing to gravity.…”

The purpose of this work was the direct numerical simulation of heat and fluid flow by granular mixing in a horizontal rotating kiln. To model particle behaviour and the heat and fluid flow in the drum, we solve the mass conservation, momentum and energy conservation equations directly on a fixed Eulerian grid for the whole domain including particles. At the same time the particle dynamics and their collisions are solved on a Lagrangian grid for each particle. To calculate the heat transfer inside the particles we use two models: the first is the direct solution of the energy conservation equation in the Lagrangian and Eulerian space, and the second is our so-called linear model that assumes homogeneous distribution of the temperature inside each particle. Numerical simulations showed that, if the thermal diffusivity of the gas phase significantly exceeds the same parameter of the particles, the linear model overpredicts the heating rate of the particles. The influence of the particle size and the angular velocity of the drum on the heating rates of particles is studied and discussed.

“…As a result, the characteristic time-step size of the DEM calculation should be much smaller than that of the MPS calculation. To cope with this problem, a multiple time-step algorithm is introduced, which was developed for numerical simulations of fluid-solid mixture flows based on the finite-volume particle method (7) . The procedure for coupling the MPS and DEM calculations is described as followings, shown in Fig.…”

“…For convenience, the initial arrangement of the five layers of cylinders in the water dam is separated by a left-upper square, a right-upper oval and a central triangle. A comparison of the mixture flows in the tank at 0.2 s for the experiment (7) and simulation using DEM is shown in Fig. 8.…”

The COMPASS code is designed based on the moving particle semi-implicit method to simulate various complex mesoscale phenomena relevant to core disruptive accidents of sodium-cooled fast reactors. In this study, a computational framework for fluid-solid mixture flow simulations was developed for the COMPASS code. The passively moving solid model was used to simulate hydrodynamic interactions between fluid and solids. Mechanical interactions between solids were modeled by the distinct element method. A multi-time-step algorithm was introduced to couple these two calculations. The proposed computational framework for fluid-solid mixture flow simulations was verified by the comparison between experimental and numerical studies on the water-dam break with multiple solid rods.

“…A review of the numerical simulations of fluid-solid mixture flows was published by Zhang et al [8]. The core of present approach can be safely characterized as a smoothed particle method [9], whereby the mixture density is smoothed by a procedure which should be immaterial for the present purpose.…”
