【Abstract】 The traditional identification methods of flow regimes were only looked as a kind of defined methods of flow regimes.In this article,a new flow pattern identification method of two-phase flow was proposed.Firstly the method analyzes the dynamic pressure-difference fluctuation signals of a flow regime by utilizing wavelet analysis and extracts the characteristics,then wavelet energy is input into betterment B Pneural network and flow regime intelligent identification can be performed.The method was demonstrated by experimental data.更多还原
