Abstract :
This paper simulates the electrical particle concentration and migration in the small diameter particles in a micro-channel using CFD. This research is a first step to visualize, concentrate and distribute particles behavior at certain cross-section and between cross section under capacitance sensing. The calculation conditions are Reynolds number influence of electrical power, and cross-section, AC, and frequency. To obtain the high quantitative information of two-phase flow, use Clausius-Mossotti theory, Navier-Stokes and Maxwell equations. As a result, particle is moved in the case of cross-sections. The result is very useful for developing a detector of thrombus in an artificial heart.
