Effect of Inhomogeneous Parallel Flow on Plasma Waves and Instabilities

Final Report Summary - SPACE PLASMA FLOW (Effect of Inhomogeneous Parallel Flow on Plasma Waves and Instabilities)

Project context and objectives

The major objective of the research project was to study the effect of non-homogeneous flow on various plasma instabilities and to see if the conventional picture of the space plasma fluctuations could be explained by the hypothesis of shear flow induced instabilities. The results we had obtained are very close to what we had anticipated, the curvature in the flow, if considered, can actually stabilise plasma instabilities which is contrary to the usual picture. This indicates that the origin of the space fluctuation needs to revisited as suggested in the present study.

This result has also major impacts on fusion plasma physics. The pioneering work is recognised internationally as the fellow was recently elected as the prestigious Fellow of the American Physical Society for his work carried out under this fellowship (quoting from his fellowship citation) "for his formulating novel theory in plasma and flow dynamics. These have opened up a new avenue for the ultimate breakthrough in the world's fusion energy research and can completely change the conventional wisdom in space science ----".
