文摘
- •
Active control of ferrofluid droplet generation in a microfluidic T-junction is demonstrated.
- •
Unsteady three-dimensional Volume of Fluid (VOF) simulation is adopted.
- •
Capillary number, dipole strength and position influence droplet shedding behaviour.
- •
Magnetic actuation of a microfluidic droplet generator is characterised.
