Development of EHD pump based on numerical simulation of electric field

Abstract

To improve the pressure output of the EHD (Electric Hydro Dynamics) pump, we conducted the numerical simulations of the electric field in the EHD pump using OpenFOAM. In addition, the proposed EHD pump was designed based on numerical results, and the pressure output of the proposed EHD pump was measured. The better proposal from the numerical results was that the electric field in the EHD pump was directed to the flow direction. In addition, the numerical results were indicated that the pressure output of the proposed EHD pump was increased by multiple sets of the electrodes. Experimental results show that remarkable pressure can be generated by proposed EHD pump.
