We examine the dynamics of turbulent reconnection in 2D and 3D reduced MHD by
calculating the effective dissipation due to coupling between small-scale
fluctuations and large-scale magnetic fields. Sweet-Parker type balance
relations are then used to calculate the global reconnection rate. Two
approaches are employed -- quasi-linear closure and an eddy-damped fluid model.
Results indicate that despite the presence of turbulence, the reconnection rate
remains inversely proportional to $\sqrt{R_m}$, as in the Sweet-Parker
analysis. In 2D, the global reconnection rate is shown to be enhanced over the
Sweet-Parker result by a factor of magnetic Mach number. These results are the
consequences of the constraint imposed on the global reconnection rate by the
requirement of mean square magnetic potential balance. The incompatibility of
turbulent fluid-magnetic energy equipartition and stationarity of mean square
magnetic potential is demonstrated.
