Abstract
There are some studies related to the interaction behavior between liquid and solid; however, there are little studies dealing with the behavior of water falling onto a concave-formed object. In this paper, we propose a method to represent the behavior of film formed by liquid falling onto a concave-formed object. This study uses a particle method called SPH (Smoothed Particle Hydrodynamics) for analyzing the behavior of liquid, and Navier-Stokes equations are solved for the simulation. In addition, the liquid particles are affected by the concave-formed object according to the distance between them. Furthermore, air resistance, surface tension, and artificial viscosity are considered to represent the behavior more realistically.
