超疏水表面上液滴撞击动力学的研究

摘要

Impacting dynamics,in relation to water droplet collision with superhydrophobic surfaces,was studied using high speed camera.Theoretical analysis,accounting for the maximum spreading factors,was given in terms of energy conservation.Also,the viscous dissipation for flowing within textured surface was taken into account.Thus,the resulting analysis was consistent with experimental results.%利用高速摄像技术研究了超疏水表面上液滴撞击过程的动力学。根据能量守恒观点理论研究了撞击液滴的最大铺展直径的关系式,理论推导过程不仅考虑了撞击过程中的表面能的变化,同时考虑了微结构缝隙中流体的粘性耗散作用,最终的理论关系式与实验结果相吻合。
