Vortex tangles under the effect of rotation were numerically studied for the first time. At velocities higher than the onset of the DG instability, the existence of a new state of superfluid turbulence (polarized turbulence) that is characterized by two statistically steady state properties, the vortex line density and the degree of polarization, was determined. Although the computed range of vortex line densities does not overlap with the much higher values obtained in the experiments, the same qualitative dependence of vortex line density versus counterflow velocity at different rotations was found.
