| Abstract: | This paper describes a multi-electrode capacitance tomography system used for two compo-nent flow imaging.When the component distribution of the flow is given.the capacitance between any twoelectrodes can be calculated through a finite clement method.Then the sensitivity distribution of the system can also be determined by this method.The image of the flow component distribution is reconstructedby using a back-projection algorithm from the calculated sensitivity distribution. |
