Abstract- It is commonly known that calculation of ionic wind is a difficult task from various points of view. Especially complex task is to take into consideration ionization processes in the sheath of corona discharge. That is why a topic of developing simplified methods of calculation corona discharge and ionic wind is actual. The new simplified method for computation corona discharge is considered. It is based on the unipolar approximation. The negative ions' flux density on the active electrode is defined by the original boundary condition. Comparison of simulation and experimental data (current-voltage characteristic, velocity field) reveals that the simplified model reproduces the basic properties and regularities of ionic wind however quantitative distinctions occur.

Keywords-Ionic wind, corona discharge, computer simulation
