【Abstract】 A method for analyzing flow Pattern using wavelet is presented. The differential pressure signals of flow in a horizontal pipe are studied by wavelet analysis. The flow pattern can be recognized easily according to the characteristics of plug flow and wave flow. Compared with other methods for recognizing flow pattern, this method needs less measurement parameters and can do instantaneously and continuously.更多还原
