A method of multi-scale distribution entropy (MSDE) in a coupled 3D phase space is proposed to uncover dynamics underlying complex systems. The performance of the MSDE is validated with Lorenz system and ARFIMA processes. The MSDE is dramatically associated with the cross-correlations of coupled time series. The MSDE is an effective tool uncovering the complex dynamic behaviors of oil–water flow pattern transitions in a horizontal pipe.
