Abstract 

  Within the vertical 2-Dimensional (2D) asymmetrical model, the blood flow transport through a narrow semicircle shape is the numerical study based on the concept of the electrokinetic flow technique. In this study, the blood flow transport has been compared to the electric field, the flow pattern, the pressure field, the vorticity, the temperature field, and the concentration field with and without the electrokinetic flow. The electrical voltage and time are varied from 0 – 20 kV and 0 – 1 s, respectively. The result has shown that the blood flow transport is moved upward within the vertical 2D asymmetrical model and the electric field has not appeared in the case of without the electrokinetic flow. With the electrokinetic flow, the flow pattern, the pressure field, the vorticity field, the temperature field, and the concentration field are not the same pattern as the electric field but they are induced by the electric field. Furthermore, at the center of a narrow semicircle shape, the electric value, the velocity, and the pressure are increased with the electrical voltage increasing but the vorticity and concentration are decreased with the electrical voltage increasing. Finally, the experimental result is compared with the numerical result, it can be seen that simulation results had good agreement with experiment results.
