An emulsion drop's impact on an inclined mesh: How far is the penetration possible?

An emulsion drop's impact on inclined meshes is studied. The drop is observed to penetrate and spread along the mesh. The penetration reduces with a rise in inclination for a height and becomes limited at the highest angle for all heights. Capillary resistance outshines inertia, making the drop penetrate less and flow along the mesh. The maximum spread rises. The spread is compared with three existing models applicable to flat surfaces. One compares well for lower inclinations, whereas the other for higher ones. The study brings out the penetration limitation for an emulsion drop's impact on inclined meshes.
