Lateral Drop Rebound on a Hydrophobic and Chemically Heterogeneous Surface

In this paper, the process of a drop rebounding from hydrophobic and chemically heterogeneous surface is investigated using multiphase lattice Boltzmann method. The bounce behavior drops dependent on degree hydrophobicity heterogeneity surface. When homogeneous, rebounds vertically height increases with enhancement hydrophobicity. For two different parts, laterally toward lower side. Because high side exerts stronger unbalanced Young’s force contact line compared low side, difference forces results in asymmetrical rebound. A phase diagram displays rebound numbers impacting various homogeneous surfaces. simply quantitative estimation made to predict heights flying times through angles This work promotes understanding mechanism provides guiding strategy for precise control lateral by
