| Research Abstract |
Collision between liquid droplets with different composition and droplet wetting on a solid surface were investigated. In the macroscopic analysis using the particle method, interfacial tensions were formulated and the collision of liquid droplet with different density, surface tension and interfacial tension were successfully simulated. Molecular dynamics simulations of the wetting of liquid droplet on a solid surface revealed the effects of electric potential of solid surface as well as of alcoholmixing on the wetting feature.
