摘要:The impact of a liquid drop on a solid surface is one of those everyday phenomena that attract the curiosity of many scientists because, despite its apparent simplicity, it conceals some nontrivial and challenging physics. The interest in understanding drop impact phenomena is also practical, because they play a major role in the optimization of several applications, such as spray applications, which are ubiquitous in industrial as well as in domestic processes, from painting or cleaning surfaces to injecting fuel into internal combustion engines.
In this seminar some recent results about the impact of non-Newtonian drops on solid surfaces are reviewed, with focus on viscoelastic fluids (dilute polymer solutions) and viscoplastic (or yield-stress) fluids.
