The present study is dedicated to the 2D steady state simulation of the ionic wind and the ozone produced by a DC corona discharge between two parallel wires in ambient humid air at atmospheric pressure. The kinetic model includes a mechanism of humid air chemistry to simulate the spatial production of ozone and charged species. The model also predicts the ionic wind velocity, in dry and humid air. The results of the 2D simulations conducted with the model are compared with measurements. In humid air, H3O + (H2O)n ions are identified as the dominant ions, as opposed to O4 + ions in pure dry air. A significant reduction of the ozone production rate is observed as the humidity increases, accompanied by a slight decrease in the velocity of the ionic wind.
