Schematic view of plasma flow stream function in a blob (moving frame).
Top: the equilibrium density profile. Bottom: coordinates of “center of mass” of the blobs as a function of time a blob initially moving towards increasing density (curve 1) and a blob moving towards decreasing density (curve 2). Dotted lines correspond to inward and outward moving blobs in uniform density plasma.
The contours of electrostatic potential plots of a blob moving in a horizontal (-) direction: along increasing density (a), a blob moving through decreasing density (b), and a blob moving along uniform density (c).
Density evolution for a blob moving in a horizontal (-) direction: along increasing density (top) and a blob moving along decreasing density (bottom).
