Project description
The project aim is the investigation of the dynamic properties of micro droplets impinging on superhydrophobic surfaces. The study must include a mapping of the oscillation modes during launch and after impact, and a comparison with existing mathematical models in the field. The experimental observations must be correlated with the structural properties of the surfaces, and the wetting properties of the surface, e.g. contact angle, contact angle hysteresis and the roll-off angle.
Content
Measurements are performed using a state of the art contact angle goniometer equipped with a tilting cradle for roll off measurements, and a high speed camera for recording of the dynamic properties. Topology characterization using SEM, AFM, and optical profilometry will be part of the project, and extensive data analysis and some mathematical modelling must be anticipated.
