Conducted computational research on Rayleigh–Bénard convection in annular geometry under the supervision of Dr. Ambrish Pandey.

• Derived and implemented governing equations based on the Navier–Stokes equations in cylindrical coordinates.
• Developed finite-difference numerical solvers for diffusion and convection problems.
• Implemented implicit numerical schemes including Crank–Nicolson and Alternating Direction Implicit (ADI) methods.
• Investigated the influence of Rayleigh number and Prandtl number on fluid flow and heat transfer characteristics.
• Simulated temperature evolution and velocity fields in buoyancy-driven convection systems.
• Performed Okubo–Weiss parameter analysis to identify vortical and strain-dominated regions in fluid flow.
• Generated contour plots and scientific visualizations to study thermal plumes, circulation patterns, and coherent structures.
• Analyzed stability and transport properties in convection-driven flows.

Reading project on Virial theorems in Astrophysics under the supervision of Dr. T.R. Seshadri.

• Tried to understand the role of gravitational potential energy and kinetic energy in determining the stability of self-gravitating systems.
• Studied applications of the Virial Theorem to star clusters, galaxies, and molecular clouds.
• Examined the relationship between energy balance, equilibrium, and gravitational collapse in astrophysical objects.
