Effects of turbulence on magnetic reconnection: 3D numerical simulations

Turbulent reconnection is studied by means of three dimensional (3D) compressible mangnetohydrodynamical numerical calculations. The process of homogeneous turbulence is set up by adding three-dimensional solenoidal random forcing implemented in the spectral space at small wave numbers with no correlation between velocity and forcing. We apply the initial Harris current sheet, configuration together with a, density profile calculated from the numerical equilibrium of magnetic and gas pressure's. We assume that there is no external driving of the reconnection. The reconnection develops as a result of the initial vector potential perturbation. We use open boundary conditions. Our main goal is to find the dependencies of reconnection rate on different properties of turbulence. Tire results of our simulations show that, turbulence significantly affects the topology of magnetic field near the diffusion region. We present that the reconnect. ion speed does riot; depend on the Reynolds numbers as well the magnetic diffusion. In addition, a fragmentation of Current. sheet decreases the disparity in inflow/outflow ratios. When we apply the large scale and more powerful turbulence the reconnection is faster.
