Theoretical analysis of linear stability of electrified jets flowing at high velocity inside a coaxial electrode

In this article we develop a temporal linear stability analysis of a circular electrified jet flowing inside a cylindrical coaxial electrode. The problem of a high-velocity jet going in a gaseous atmosphere is examined and we analyze the results in order to bring out the influence of the electrification, the surface tension, the velocity and other parameters on the stability of the jet; From this theory we finally state the changes in the breakup phenomena that are expected to be observed when electrifying these jets.
