Sensitivity of Small Scale MHD Turbulence to Velocity-Magnetic Field Correlations

V.v = 0 ; V.b = 0 In order to stress the internal dynamics instead of effects due to special geometries, we used periodic boundary conditions. In this case, spectral methods based on Fourier series expansion are particularly useful, because they are both economical and precise. We used 2 2 resolutions of (256) and (512) collocation points. The Prandtl number Pr = v/r, was taken equal to unity and no background magnetic field was present. Special attention was devoted to the dynamical influence of velocity-magnetic field correlations ("cross-
