In nuclear engineering, solid particles are associated with numerous processes, such as
solid–fluid flows in pebble bed reactors, coating during fuel fabrication, and debris bed …

Gas–solid–liquid three-phase flow systems are ubiquitous in chemical and energy
engineering. To simulate the multiphase systems, the authors' group has developed a …

Free-surface flow coupled with solid-liquid phase change can be observed in many
industrial applications, and it has a great influence on many industrial processes. In this …

Axisymmetric flows are widespread problems in the engineering field, but doing complete
3D simulations for them is very time-consuming. This study aims to develop an axisymmetric …

Porosity is a key issue for the parts fabricated by selective laser melting. However, the
porosity formation mechanisms have not been fully clarified. In particular, the formation of …

Dissolution characteristics of solutes with different shapes are studied. To simulate the
process of dissolution, a diffusion and dissolution model based on the moving particle semi …

Fluid–rigid body interaction is a significant topic in research on particle methods. This study
