High speed camera investigation of the impingement of single water droplets on oxidized high temperature surfaces

► The behavior of droplet impacting on high temperature surfaces was experimentally investigated. ► The liquid-solid contact time increases with increasing oxide layer over the hot surface. ► The spreading diameter decreases with increasing oxide layer over the hot surface. ► The spreading diameter mainly increases with increasing droplet Weber number. ► New empirical correlations have been deduced describing droplet impacting on oxidized surface.
