Visualization of Free Fall Particle Density Distribution by CT and 3D-Wavelet

Abstract

This study evaluates particle density distribution images in a pipe cross-section by means of 3D-wavelet transform that is a parameter to indicate the dominant transition among CT time-space frames. It is clarified a time level 5 and space level 3 is the most particle density transition. The density distributions of solid-air two-phase flow with a time-space transition are measured by a capacitance CT.
