This paper deals with the numerical modelling of corona discharges induced by electrohy-drodynamic actuators. A specific numerical method is proposed and discussed to compute the multiscale nature observed in the modelling of corona discharges. The idea consists in a domain decomposition of the computational domain where each subdomain is described with a(More)
This paper deals with the modelling of plasma discharges induced by electrohydrodynamic actuators. We propose a multi-model method based on fluid conservation equations that allows an increase of the maximum time step imposed by usual explicit schemes. The idea consists in replacing the numerical integration of the plasma equations at the vicinity of the(More)
A mechanical spike is a device used to mechanically act on the bow shock ahead of an airplane in supersonic ight. This action results in improved ight conditions. We will investigate here the eects of the axial generation of a two-hundred-micrometer width cylindrical plasma ahead a quasi-realistic nose prole of centimeter width. The device is named plasma(More)
