Kinetic energy density color maps. Kinetic energy density is shown in red and highlights the flare loops, the current sheets, and shocks traveling through the surrounding atmosphere. Overlays show the electron acceleration energy densities in green and the energy deposition density in blue. Energy densities for all panels of this figure have a lower saturation limit of 10⁻¹ erg cm⁻² s⁻¹ and an upper limit of 10³ erg cm⁻² s⁻¹. The columns from left to right show results for the experiments with background magnetic field strengths of B₀ = 20 G, 35 G, 50 G, and 65 G, respectively. The top row shows the simulations at the time after the impact of the leading edge of the reconnection outflow jet. This impact and its reflection causes hot upflows from the chromosphere. The second row shows the time at which the flare loops have rebounded after their compression during the impact. The third and fourth rows show later times, when the loop tops settle and exhibit turbulent eddies on alternating sides of the central line (that is, a magnetic tuning fork process). An animated version of the figure is provided in the online materials.
