A blob-filament (or simply “blob”) is a magnetic-field-aligned plasma structure which is
considerably denser than the surrounding background plasma and highly localized in the …

In this paper we review some theoretical aspects of the dynamics of the mesoscale filaments
extending along the magnetic field lines in the edge plasma, which are often called 'blobs' …

Plasma 'blobs', which are localized enhanced density structures, have been widely
observed in the turbulent edge and scrape-off layer (SOL) of several tokamaks. They are …

Radial convection of isolated filamentary structures due to interchange motions in
magnetized plasmas is investigated. Following a basic discussion of vorticity generation …

High-speed high-spatial-resolution data obtained by the gas puff imaging (GPI) diagnostic
on the National Spherical Torus Experiment [M. Ono, MG Bell, RE Bell et al Plasma Phys …

Nonlinear three-dimensional electromagnetic simulations are employed to study the
dynamics of edge localized modes (ELMs) driven by intermediate wavelength peeling …

Numerical fluid simulations of interchange turbulence for geometry and parameters relevant
to the boundary region of magnetically confined plasmas are shown to result in intermittent …

Three-dimensional and two-dimensional seeded blob simulations are performed with five
different fluid models, all based on the drift-reduced Braginskii equations, and the numerical …

Dynamics of blobs described by two different models for the closures of parallel plasma
current is studied numerically. One of these closures describes the blob sitting on magnetic …

Simulations have been carried out to establish how electron thermal physics, introduced in
the form of a dynamic electron temperature, affects isolated filament motion and dynamics in …
