Abstract：Ionic wind from atmosphere discharge is a neoteric technique, which has inimitable advantages than present technologies in practical application. By adopting the PIV(Particle Image Velocimetry) system, images of ionic wind velocity field are pictured clearly and accurately. The research results indicate that higher speed of ionic wind can be achieved by decreasing the curvature radius of the pin electrode, being applied the same class of voltage, and that high speed of ionic wind can be obtained with lower voltage as well as the effective area and the velocity field of wind are vast and even, which are resulted from the grounding metal net electrode, declining the restriction to the ionice wind.
