Abstract
By employing X-ray photography and image analyses, internal three-dimensional flow field of a simulated solid propellant slurry containing lead sphere tracers is visualized in a double circular cylinder container. X-rays are projected on to the slurry flow from two directions perpendicular to each other and penetration images are recorded by a flat panel detector and an X-ray image intensifier. By suppressing the mutual interference of the X-rays, the two-directional X-ray photography has been successfully conducted. Using the time series data of the X-ray images from the two directions, the identification of each tracer particle in space and time has been done and their three-dimensional paths have been computed. From these procedures, the flow field or the velocity field inside the opaque slurry flow has been estimated.
