Abstract:
1. Device generating a plasma flow comprising an electrically conductive housing, tubular in shape, connected to the earth and forming a central channel traversed by a vortex gas, a central electrode arranged coaxially in said channel and an electric power source connected to the central electrode and to the earth, said electric power source being adapted to apply an electric voltage V between the electrode and the housing, wherein the mean diameter of the channel formed by the housing decreases progressively from an area situated substantially at the level of a free end of the electrode as far as an end area of said housing, wherein said end area defines an end channel oriented along the longitudinal axis of the housing, said end channel opening out onto an open end through which the plasma flow exits, wherein said open end has a section of conical shape and defines partially a surface in three dimensions described by the equation:
