Overview

Experimental study investigates the evaporation characteristics of SiO2 nanofluid droplets, revealing surfactant influence on dynamics.

Key Points

  • Higher concentration of SiO2 nanoparticles accelerates evaporation kinetics.
  • The addition of sodium dodecyl sulfate reduces surface tension, promoting evaporation.
  • Droplets with SDS exhibit lower Leidenfrost temperature than those without surfactants.
  • Dynamic processes of droplet impact include stages of deposition, spreading, and stable evaporation.
