Measurement And Studies Of Two-Phase Flow Parameters Based On Information Fusion

This paper has put forward a new method of recognizing two-phase flow type based on multi-sensor information fusion. Recognizing flow type by information fusion arithmetic on the base of capacitance sensors as the complexity and random of two-phase type. It will eliminate the handicap of slow speed and elevate the correction of recognizing flow type by Displacing the traditional arithmetic . It will provide a new method of creating model and measurement to the special parameters in some difficult system. This article is also the development and exploration of two-phase flow measurement and information fusion.To the object of two-flow,we trace its dynamic character and measure its correlated parameters by eight-electrode capacitance sensors. Then turning the dispersed information to the integral information by sufficiently using information of object. The simulation experiment proved that this information fusion arithmetic can recognize the flow type precisely and timely.To the concrete two-phase flow -crude oil, its temperature, speed and capacitance value are measured by flat capacitance sensors, FLUKE RLC instrument and other auxiliary appliance. Assessing the characters of crude oil and predicting the solidifying point is the result of using fuzzy information arithmetic.The information fusion arithmetic can use the effective information synthetically to acquire the knowledge of the object. So it can reduce the influence of error and obtain more information of supporting the object. In all, this arithmetic will be valuable and potential, it has provided a new and effective method of measuring two-flow type.
