Fig. 4


Total helicity flux, Ftot (Eq. (30)), and the terms compositing it, Eqs. (26)(29), through the different boundaries computed in the practical DeVore gauge. a) Ftot; b) Fφ; c) FAAp; d) FBn; and e) FVn. In each plot the dark line corresponds to the sum of the flux through all the boundaries, while the color lines correspond to a flux through a particular boundary (purple and blue: left and right x sides, green and orange: front and back y sides; yellow and red: bottom and top z sides).

This figure is made of several images, please see below:
