A TWO-PHASE FLOW BOUNDARY DETECTION METHOD BASED ON CT SYSTEM
Computerized Tomography(CT)is very suitable for multiphase flow measurement.The only problem is long processing time against fast real time flow change.It is possible to improve CT systems speed by narrowing image processing area interested.The pipe lines space geometry is known.It is a static system without flow through it.Use a slow but accurate algorism to reconstruct pipelines slice picture as system pre-calibration.Then acquire real time flow data,reconstruct slice picture contained real time flow information.Combined with pre-calibration to get the real-time slice picture of water envelope which provide information available for further flow calculation.
