Abstract
Particle distribution in a pipeline has been clearly visualized by a combination of a capacitance-computed tomography and 3D wavelets multiresolution. As a result, the steady and unsteady particles are decomposed to extract the dominant frequency level. The CT obtains the capacitance between 12 electrodes distributed around the outside of the pipeline. The particle and air distributions can be separated because of individual permittivity by the reconstruction technique. The technique calculates the permittivity distribution on the cross section from the capacitance values by an iterative method of inverse problem.
