Abstract :
A computerized tomographic method is described for imaging the component distribution in two-component flow processes. It uses eight capacitance electrodes arranged around the flow pipeline to scan the flow, and a linear backprojection algorithm is developed to reconstruct the cross-sectional image of the flow from 28 measured capacitance values. This method has the advantage of being nonintrusive to the flow, inexpensive, and simple to implement, and hence is promising for industrial applications. A prototype system based on this method has been developed and images of static physical models have been obtained
