摘要:
The problem of the shape of an annular charged jet in an external electric field is considered. In the strong-field approximation, the formulation of the problem is reduced to a system of ordinary differential equations. The asymptotics of the solutions at large distances from the point of outflow are investigated. The condition of formation of the jet profile non-increasing along the streamwise coordinate is found.
