Simulation of the discharge propagation in a capillary tube in air at atmospheric pressure

Original language description

This paper presents simulations of an air plasma discharge at atmospheric pressure initiated by a needle anode set inside a dielectric capillary tube. We have studied the influence of the tube inner radius and its relative permittivity epsilon(r) on thedischarge structure and dynamics. Our simulations indicate that the geometrical constraint of the cylindrical tube has more influence than the value of epsilon(r) on the discharge structure and dynamics.We have studied the influence of photoemission processes on the discharge structure by varying the photoemission coefficient. The photoemission, as it increases the number of secondary electrons close to the dielectric surface, promotes the tubular structure of the discharge.
