We numerically study the chiral turbulence of rotating neutrino matter in the core of supernovae. The rotation yields inverse cascade and the novel current along the direction of rotation called the chiral vortical effect. We for the first time demonstrate that the chiral vortical effect induces a flow in the direction of vorticity and a conversion from fluid helicity to neutrino density. These results may potentially lead to asymmetrical supernova explosions and the increase in the explosion energy in three-dimensional simulations.
