论文摘要
尽管对空气中液滴变形的非线性电水动力学进行了严格的分析，但其对周围气相的影响却较少。我们观察到，由于吊坠水滴的较大变形振荡而产生的空气循环作用，受到谐振电场的影响，就像在液滴周围空气中的微型或迷你鼓风机一样。当将其放置在气溶胶中时，强烈的静电空气颗粒捕获在液滴上的恶化来证明这一点。如此强大的局部空气动力学对两相系统中的气溶胶颗粒物，热量和传质的影响引起了人们对基本和技术研究的进一步兴趣。
Despite a rigorous analysis of nonlinear electrohydrodynamics of a liquid droplet deformation in air, its influence on the surrounding gas phase has received less attention. We observed, air circulations created due to large deformation oscillations of a pendant water droplet subject to a resonating electric field act like a micro or mini blower in the air around the droplet. This is demonstrated through the deterioration of a strong electrostatic airborne particulate capture onto the droplet, when it is placed in an aerosol. Such strong local aerodynamic influence on the surrounding aerosol particulate, heat and mass transfer in the two phase system provoke further interest in fundamental and technological research.
