Ferrofluid droplet generation on a zero-thickness nozzle by a magnetic field using a wedge-shaped functional surface
Fig 7
(a) Dimensionless diameter and (b) droplet generation frequency versus the magnet distance from the vertex of the hydrophilic surface for different ferrofluid injection rates and the triangle vertex angle of 10°.
Each measurement is an average of at least five droplets. The standard deviation is significantly small and is not visible.
