Density ρ (color scales) and magnetic flux (solid lines) contours as reconnection progresses in different Rm environments: (a) , (b) , and (c) .
Plasmoid flux distribution function for different Rm . The dashed straight line represents .
Plasmoid width distribution function for different Rm . Here, wx is the full width of each plasmoid measured in the x-direction across the current sheet. The dashed straight line corresponds to .
Plasmoid mass distribution function f(m) for different Rm . Here, m is the amount mass contained inside each plasmoid. The dashed straight line shows an m −2 power law for reference.
Plasmoid width distribution in two directions for the case of . Here, wz and wx are the widths of each plasmoid along the z-and x-directions, respectively. Color-bar indicates the mass contained in each plasmoid.
Distributions of magnetic energy density Em along the z-axis (a), and the corresponding Fourier power spectrum (b). The straight line in (b) is the fitting of a power law function to the experimental data with index of 2.92.
Same as Fig. 6 , but for the kinetic energy.
(a) Variations of and versus time for . The solid line is for and the dashed line is for . (b) Variations of and of simulation box versus time. The solid line is for and the dashed line is for . The arrows in both panels specify the time when the non-linear stage begins.
Dependence of the Fourier power spectrum indices on Rm : (a) versus Rm , and (b) versus Rm . The solid lines are for the spectral index averaged over a given time interval when the total electric current density is close to its maximum, and the dashed lines are for the index at maximum.
Magnetic energy spectrum becomes steeper with the growth of magnetic islands. (a) The distributions of density ρ along the center of the current at different times, which shows that the new magnetic islands form and grow rapidly during this period; (b) The distribution of magnetic energy at t = 32.5 and t = 33.0; (c) and (d) are for magnetic energy spectrum at initial and final time.
Magnetic energy spectrum becomes steeper with the merging process of magnetic islands. (a)–(d) are same as Fig. 10 .
Magnetic energy spectrum becomes shallower when the large scale magnetic islands move out the system. (a)–(d) are same as Fig. 10 .
