Research Abstract
The aim of this study is to elucidate the role of flows along the magnetic field in exciting various secondary structures in plasmas. The previous research reports the modulational instability of perpendicular flows can be controlled by the parallel flows. This study has been extended to the case of spectrum waves, where density modulation has been found to be relevant to excite radial streamer flows. 3D helical flow structures are also excited in turbulent plasmas and the flow helicity can be used to quantify its excitation.
