A Lagrangian method is introduced to analyze the tip leakage vortex (TLV) behavior in a low-speed axial compressor rotor. The finite-time Lyapunov exponent (FTLE) fields are calculated based on the delayed detached-eddy simulation (DDES) results and

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-equi
