Application of Radiographic Techniques to Studies of Particle Laden Flow

Abstract

Attenuation of X-radiation is used to measure powder density in flowing systems. The report describes the experimental absorption and procedures used to make such measurements. A discussion is given of the effect of the X-ray intensity spectrum on the effective absorption coefficient of the powder. An error analysis is presented, and maximum and minimum density measurements for the experiment are calculated. The absorption experiment gives the value of powder density, rho, multiplied by absorption path length, l. Radiographs, density contours, and radial density profiles from multicomponent vortex flow experiments are presented.
