The drop impacting on the hydrophobic/superhydrophobic surface was simulated by computational fluid dynamics method.Influences of drop dripping height,wettability and surface’s incline angle on droplet moving were analyzed.The results show that,with the increasing of dripping height,the spreading coefficient is increased,the rebounding coefficient is decreased,and the influence of dripping height on spreading coefficient and rebounding coefficient will be stronger when the hydrophobicity is enhanced.With the enhancement of surface hydrophobicity,the spreading coefficient is decreased but the rebounding coefficient is increased,and the influence of hydrophobicity on spreading coefficient and rebounding coefficient will be weakened by the increasing dripping height.The larger the incline angle is,the smaller the spreading coefficient and the rebounding coefficient,and the bigger the maximum velocity inside the droplet.
