A Study of Different Fluid Droplet Impacting on Dry and Wet Surface

Abstract:

The droplet impacting on dry and wet surface is studied. Splashing was not observed with the impacting velocity up to 600 cm/s for vertical impingement on dry solid surfaces. Transition to splashing happens when the steel surface is wetted and the dry surface is inclined. There is a relationship between the impacting angle and impacting velocity for the transition boundary. The transition impacting angle increases with the increase of the impacting velocity.
