A computer model of the ionic wind in the unipolar approximation with the boundary condition on the ion flow variation rate

详细

A new simplified model of the ionic wind in air is presented. An expression for the electron flow variation rate at the outer boundary of the corona sheath is obtained. It is shown that, in order to simulate the ionic wind in the case of the negative polarity of the high voltage electrode, not only negative ions but also electrons should be taken into account in the external zone. The proposed and the traditional computer models of the ionic wind in the point–torus system are compared.
