Numerical investigation of the role of linear and nonlinear forces in determining the direction of electric wind caused by atmospheric pressure DC corona discharge

In this study, the force generated by atmospheric positive and negative corona discharges was investigated using a simulation of wire–cylinder configuration. We provided new insight into discharge introducing nonlinear on charged particles in vicinity wire electrode. To elucidate origin both forces discharges, we performed 2D simulations via COMSOL Multiphysics MATLAB software. It observed that direction is always from to cylinder regardless applied voltage polarity. illustrated corresponding larger than discharge. However, span greater The numerical results showed that, addition linear (Coulomb force), strong around electrode (powered electrode) plays complementary role production electric wind caused As limited electrode, it possible ignore with good approximation calculation total electrohydrodynamic force, but cannot be ignored process forming wind.
