Non-flow-pattern dependent method study for velocity profile estimation using a electrical capacitance tomography

Abstract

This paper presents an study of the non-flow-pattern dependent method permitting a solid velocity field to be unambiguously calculated with higher robust using a twin-plane electrical capacitance system. It is based on a spectrum analysis of the pixel values of both cross-sections of the tomographic system. The numerical results of flow velocity measurement using the proposed method against the correlation method are presented.
