During the fellowship term, collaboration with Dr. K. R. Sreenivasan introduced me to the topic of magnetic reconnection. In this context, I have been working on planar Magnetohydrodynamic (MHD) jets subjected to an in-plane transverse velocity perturbation. The Kelvin-Helmholtz (KH) instability that ensues can result in magnetic reconnection in certain flow regimes. My initial work has been on identifying the specific regimes in which the magnetic reconnection is observed, and I have been analyzing the effect of compressibility and magnetic field orientation on the stability of the planar jets. 3D simulations using Magneto Gas Kinetic Method (MGKM) are used for this analysis. MGKM takes into account the non-ideal MHD terms for finite plasma conductivity, and Hall effects which inculcate two- fluid effects into the single fluid MHD approach. An abstract titled ‘The effect of compressibility on magnetohydrodynamic jets and Kelvin-Helmholtz instability’ has been prepared and is ready for submission for the annual meeting of American Physical Society, Division of Fluid Dynamics in November 2015. This fellowship has also enabled me to take five courses during the second year of my graduate study without having to compromise on research productivity. These courses laid a strong foundation which will help guide my future research. Collaboration with Dr. Sreenivasan is certainly going to extend beyond the fellowship term.
