Flow pattern identification of gas-liquid flow based on the hybrid model of multi-scale information entropy feature and LS-SVM

Based on the characteristic that the Empirical Mode Decomposition (EMD) can decompose signal adaptively, a flow pattern identification method based on EMD multi-scale information entropy was put forward. Firstly, the acquired pressure-difference fluctuation signals are decomposed through EMD, and th...
