  The plasmoid-induced-reconnection model explaining solar flares based on
bursty reconnection produced by an ejecting plasmoid suggests a possible
relation between the ejection velocity of a plasmoid and the rate of magnetic
reconnection. In this study, we focus on the quantitative description of this
relation. We performed magnetohydrodynamic (MHD) simulations of solar flares by
changing the values of resistivity and the plasmoid velocity. The plasmoid
velocity has been changed by applying an additional force to the plasmoid to
see how the plasmoid velocity affects the reconnection rate. An important
result is that the reconnection rate has a positive correlation with the
plasmoid velocity, which is consistent with the plasmoid-induced-reconnection
model for solar flares. We also discuss an observational result supporting this
positive correlation.
