Mutual coherent structures for heat and angular momentum transport in turbulent Taylor-Couette flows

When subjected to a radial temperature gradient, Taylor-Couette flows undergo evolution of flow states with increasing rotations: first transition from asymmetric vertical convection spiral vortices, and second turbulence characterized by Taylor vortices. In the latter turbulent state, transport heat angular momentum exhibits similar power-law scaling. Our data analysis spatial distributions flux densities reveals mutual structures through which both are transported efficiently.
