  In this paper we study the enstrophy transers in helical turbulence using
direct numerical simulation. We observe that the helicity injection does not
have significant effects on the inertial-range energy and helicity spectra
($\sim k^{-5/3}$) and fluxes (constants). We also calculate the separate
contributions to enstrophy transfers via velocity to vorticity and vorticity to
vorticity channels. There are four different enstrophy fluxes associated with
the former channel or vorticity stretching, and one flux associated with the
latter channel or vorticity advection. In the inertial range, the fluxes due to
vorticity stretching are larger than that due to advection. These transfers too
are insensitive to helicity injection.
