| Research Abstract |
It was elucidated that the surface geometry of the solid particles has a dominant influence on the particle attachment to the gas-liquid interface by the numerical analyses, which were performed with the numerical methods developed in this project. The development of the numerical method was focused on the description of the moving three-phase contact line and the liquid film flow between the gas-liquid interface and the solid surface. On the reduction of computational cost and the elucidation of the dominant physical factors in the liquid film rupture is required more study in the future. To enhance the reusability of the code, the numerical methods were implemented with template, virtual function and operator overloading.
