Velocity derivative skewness and its budget in non-equilibrium time-reversed turbulence
The velocity derivative skewness and its budget equation are analysed in non-equilibrium time-reversed turbulence. We show that the positive skewness is related to the behaviors of backward energy transfer and enstrophy divergence during the non-equilibrium procedure. A dynamic equilibrium state of...
