摘要
利用小波分析理论来分析气液两相流压差波动信号的奇异性,提出一种利用小波分析的Lipschizs指数与信号的能量特征相结合的识别方法,可以识别出水平管内气液两相流的四种流型。
The singularity of the differential pressure fluctuation signal of the gas-liquid two-phase flow is analyzed by the wavelet analyzing theory.A discrimination method that combines lipschiz exponent based on wavelet analyzing and energy characteristic of isignal is proposed.The method can identify the four flow regimes of gas-liquied two-phase flow in horizontal pipe.
