Ion wind flow induced by corona discharge has been widly studied for its advantages of micro cooling. However, it is very difficult to predict the cooling performance of the ion wind for various conditions because of its complex electrohydrodynamic system. Thus, a reliable numerical modeling is required to design an otimal ion wind generator and calculate the velocity of the ion wind for the cooling performance. The numerical modeling of the ion wind has been applied and newly modified to calculate the veloctiy of the ion wind flow by combining three basic models such as electrostatics, electrodynamics and fluid dynamics. The model has included presence of initial space charges to calculate transfer energy between space charges and air gas molecules using a developed space charge correlation in this study. The simulation has been performed for a symmetrical geometry of a wire to parallel plate electrodes. The results of the simulation have been compared with the experimental data for the ion wind velocity to confirm the accuracy of the modified numerical modeling and to obtain the optimal design of the ion wind generator. As a result, a verified numerical analysis method has been developed for simulating the ion wind.
