Narrow Results

The surface hydrophilicity affects the movement of the droplet intensively when the droplet impacting on a wall, In this paper, the motion of the droplet after impacting on the superhydrophobic wall were researched by using the combined Level Set-VOF method for gas-liquid interface tracking. The results show that, the droplet would rebound after impacting on the superhydrophobic wall when the velocity is small: the droplet would breakup after when the velocity is larger; the droplet would breakup during spreading when the initial diameter is larger and less surface tension: impact angle affect the movement of the chop-let intensively after impacting on the wall. At the same time, this paper obtains critical conditions of rebound an breakup after droplet impacts on the superliydrophbic wall by vertical or inclined angle through numerical simulation in a certain range of condition.
