摘要

在本文中，我们展示了水滴与具有疏水特性的微结构表面的静态和动态相互作用。研究了两种不同直径(d0 = 0.6±0.1 mm和d0 = 2.6±0.1 mm)的液滴在0.1 ~ 2.5 m/s范围内的冲击速度。这使得研究重力对撞击过程中碰撞行为的影响成为可能。本研究的主要结果是确定了每个被研究表面几何形状的连续过渡导致各种液滴反弹情景的临界条件。

Droplet bouncing on the surface with micro-structure

In this paper, we present static and dynamic interactions of water droplets with a micro-structured surface that exhibits hydrophobic properties. Droplets with two different diameters ( D 0 = 0.6 ± 0.1 mm and D 0 = 2.6 ± 0.1 mm) were studied for impact velocities in the range of 0.1 ÷ 2.5 m/s. This allowed to investigate the influence of gravity on the collision behavior during an impact. The main result of the present research is the determination of the critical conditions for consecutive transitions leading to various scenarios of droplet rebound for each of the investigated surface geometry.

期刊介绍： Archives of Mechanics provides a forum for original research on mechanics of solids, fluids and discrete systems, including the development of mathematical methods for solving mechanical problems. The journal encompasses all aspects of the field, with the emphasis placed on: -mechanics of materials: elasticity, plasticity, time-dependent phenomena, phase transformation, damage, fracture; physical and experimental foundations, micromechanics, thermodynamics, instabilities; -methods and problems in continuum mechanics: general theory and novel applications, thermomechanics, structural analysis, porous media, contact problems; -dynamics of material systems; -fluid flows and interactions with solids. Papers published in the Archives should contain original contributions dealing with theoretical, experimental, or numerical aspects of mechanical problems listed above. The journal publishes also current announcements and information about important scientific events of possible interest to its readers, like conferences, congresses, symposia, work-shops, courses, etc. Occasionally, special issues of the journal may be devoted to publication of all or selected papers presented at international conferences or other scientific meetings. However, all papers intended for such an issue are subjected to the usual reviewing and acceptance procedure.
