Electromagnetic filament coalescence as magnetic island merging with diamagnetic effects
Souvik Mondal, N Bisai, Abhijit Sen +1
We investigate the nonlinear coalescence of two current-carrying ELM filaments using a three-dimensional electromagnetic fluid model. In the flat-density limit, the coalescence exh…

Nonlinear Dynamics of Current-Carrying ELM Filaments: Spiral Vorticity, Rotation, and Velocity Suppression
Souvik Mondal, N Bisai, Abhijit Sen +1
In this work, we investigate the nonlinear dynamics of isolated current-carrying edge-localized mode (ELM) filaments using a reduced electromagnetic fluid model in slab geometry. N…

Finite Ion Temperature Effects on the Merging of Current-Carrying ELM Filaments in the edge region of a tokamak
Souvik Mondal, Nirmal Bisai, Abhijit Sen +1
Edge-localized-mode (ELM) filaments are crucial for cross-field transport at the tokamak edge; yet, their dynamics are often analyzed using the cold-ion approximation, despite expe…
