Contribution
It provides experimental data and numerical validation on the influence of SDS and C11E5 surfactants on water droplet wetting behavior on glass.
Findings
Surfactants alter surface tension and contact angles.
Numerical simulations agree with empirical measurements.
Insights into surfactant effects on wetting phenomena.
Abstract
The experimental survey of the water drops to different concentrations from non ionic surfactant (C11E5) and set down anionic (SDS) on glass horizontal surfaces has been made. The 1st step consisted in measuring the tension of surface, the 2nd allowed us to determine the influence of these surfactants on the physical parameters of wetting (contact angle ...).The numeric simulation of the equation of profile of the drop allowed us to validate the empirical results found.
