Numerical relaxation of a 3D MHD Taylor - Woltjer state subject to abrupt expansion
Rupak Mukherjee, Rajaraman Ganesh
Since the advent of Taylor-Woltjer theory [J B Taylor, PRL, 33, 1139 (1974), L Woltjer, PNAS, 44, 489 (1958)], it has been widely believed that situations with perfectly conducting…
Recurrence in three dimensional magnetohydrodynamic plasma
Rupak Mukherjee, Rajaraman Ganesh, Abhijit Sen
We report on a numerical observation of recurrence phenomenon in a three dimensional magneto-hydrodynamic (MHD) plasma for certain classes of initial flow profiles. Our simulations…
Coherent nonlinear oscillations in magnetohydrodynamic plasma
Rupak Mukherjee, Rajaraman Ganesh, Abhijit Sen
Single fluid magnetohydrodynamic (MHD) equations have been studied through direct numerical simulations (DNS) using pseudo-spectral methods in two as well as three spatial dimensio…
Three Dimensional Pseudo-Spectral Compressible Magnetohydrodynamic GPU Code for Astrophysical Plasma Simulation
Rupak Mukherjee, Rajaraman Ganesh, Vinod Saini +3
This paper presents the benchmarking and scaling studies of a GPU accelerated three dimensional compressible magnetohydrodynamic code. The code is developed keeping an eye to expla…
Correlation between two non-linear events in a complex dusty plasma system
Rinku Mishra, S. Adhikari, Rupak Mukherjee +1
A phenomenological model using fluid theory is developed to show that the decay of two seemingly independent nonlinear structures namely the dust void and dust soliton strongly dep…
Compressibility effects on quasistationary vortex and transient hole patterns through vortex merger
Rupak Mukherjee, Akanksha Gupta, Rajaraman Ganesh
The effect of compressibility in hydrodynamic vortex merging has been discussed. In the past, in incompressible limit it has been observed that the merging of a collection of inten…
