A non-coalescence behavior of a droplet deposited near a moving wall is simulated using a three-dimensional incompressible SPH method. Interactions between gas-region and liquid-region are computed by calculating the pressure field of gas-region and giving it to the surface of liquid-region. When a droplet is released above a wall moving at a constant speed, it keeps levitating without touching the wall. Visualization of the flow field indicates that the pressure between the wall and the droplet becomes higher so that the droplet can obtain the lift force to float away from the wall.
