Abstract:

The emerging ionic liquids can be used in microfluidics due to their good photoelectric properties and non-volatile features. The flow characteristics of ionic liquids under electromagnetic drive are studied with two theoretic methods. The theoretical results are compared with experimental data. It is found that numerical results based on the finite voxel elements agree with the experimental data, while that based on the Poiseuille's law do not. Therefore, the Poiseuille's law is not a good choice in studying electromagnetic drive of ionic liquids. Flow characteristics in differently-shaped channels are investigated by numerical simulation. This research is useful in microfluidic applications of ionic liquids.

Key words: Lorentz force, microfluidics, electromagnetic drive, ionic liquids
