Abstract
The effects of the liquid trapped in a mesh on droplet penetration were investigated. It was found that penetrations could be entirely suppressed by the trapped liquid. A model for predicting the transition thresholds is proposed and compared with experimental results. It is suggested that the impact type is determined by the momentum exchange between the impacting droplet and the liquid trapped in the mesh.
