文摘
- •
A drop in a non-uniform AC electric field undergoes oscillatory deformation and dielectrophoretic motion.
- •
Initial lag during orientation of dipoles is responsible for the drop's delayed response to the applied field.
- •
Effect of applied frequency on the shape evolution and dynamics of drop is governed by charge relaxation time.
- •
Oscillatory drop deformation plays a significant role in the dielectrophoretic motion.
