Flow Velocity Profile near a Moving Three-phase Contact Line

Overview

A06 focuses on the measurement of flow profiles in complex liquids near the three-phase contact line using microscopic particle tracking. The aim is to clarify how e.g. local layer formation in suspensions, shear thinning or thickening affect the wetting dynamics and vice versa. In dewetting, a distinction must be made between pinning and non-pinning. Results will be compared with those of complementary experiments on complex surfaces. This will provide validation data for model development and simulation in different situations.
