Abstract

Mesoscale dissipative particle dynamics was used to model a nanofluid system considering electrostatic interaction. The effects on the droplet static contact angle of the concentration and charge quantity of the nanoparticles were investigated. Computational results were qualitatively agreed with experiments.
