The Role of Relative Density Difference in the Evolution and Dynamics of Drop Impact Vortices in the Intrusive Mode
摘要
Abstract
The role of the difference in the densities of the contacting media of the drop impact in a deep fluid in the intrusion mode, when the kinetic energy of the droplet is less than the potential surface energy, is studied using high-speed video recording. The evolution and dynamics of the intrusion and vortex rings are assessed when a weak aqueous solution of potassium permanganate and ethanol merges with pure water and solutions of table salt.
