The results of EHD flows in a thin gap (1 mm width) with irregular electrodes and constant external electric fields are presented. The liquid was solution of a transformer oil with iodine. The conductivity was unipolar due to electro-chemical injection of negative ions from the cathode. The flow lines were observed using a microscope. The EHD flows represent micro vortexes with an overage velocity 10 cm/s at voltage 3 kV.
Keywords: injection, voltage, liquid, dielectrics, EHD flows, electric charge, electrode.
