Adding an azimuthal velocity component to a stream coming out from a circular orifice leads to a swirling jet. Swirling jets are among the most common jet topologies present in industrial applications mostly thanks to their ability to enhance heat transfer [Huang, L. and El-Genk, M.S., 1998, International Journal of Heat and Mass Transfer, 41.3, pp.583-600]. They are usually made by means of helicoidal insets installed in the nozzle outlet. Given their versatility of use and their low intrusiveness, plasma actuators (PAs) have been considered as flow control devices in jet flows; although, mainly for aeroacoustics purposes [Crawley, M., Kearney-Fischer, M.
