Using quantitative flow visualization and a transparent microfluidic platform replicating the
salient features of the cathode channel of a polymer electrolyte membrane fuel cell …

Three-dimensional particle tracking velocimetry (3D-PTV) technique is widely used to
acquire the complicated trajectories of particles and flow fields. It is known that the accuracy …

The removal of droplets on surfaces by an (air-) flow is relevant, eg, for cleaning processes
or to prevent corrosion or damage of electronic devices. Still the condition for droplet …

A sessile water drop exposed to an air flow will shed if the adhesion is overcome by the
external aerodynamic forces on the drop. In this study, shedding of water drops were …

Sessile drops play an important role in nature and the operation of many technical and
biological systems as for instance fuel cells, cleaning processes, lab-on-a-chip devices and …

Proper water management in proton exchange membrane fuel cells (PEMFCs) remains a
challenge, hindering the commercialization of this technology. Liquid water emerges in the …

Imaging-based measurements through fluctuating phase boundaries such as free water
surfaces or droplets have usually a higher uncertainty due to the changing refraction of light …

Adhering droplets in shear flow start to move downstream when a critical velocity u crit is
reached, ie the adhesion force is overcome by aerodynamic force. It is still not clear, whether …

Among the numerical studies on liquid water transport in proton exchange membrane fuel
cells (PEMFCs), the static contact angle (SCA) model is generally used, while the dynamic …

This paper reports on the hydrodynamic droplet instabilities of different sizes and viscosities
due to shear forces in a rectangular channel. Water‐glycerine droplets of different volumes …
