| description |
The accurate measurement of flow parameters often depends on sensor accessibility. Optical flow assessment techniques, such as Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV), are limited to optically transparent media. However, many industrial processes involve opaque media, necessitating alternative methods. This study presents the development and application of X-ray Particle Tracking Velocimetry (XPTV) to investigate flows within such media. Specifically, the flow inside a nozzle of a Fused Filament Fabrication (FFF) printer was examined. A novel contribution of this work is the first-time analysis of heated flow using XPTV, achieved by introducing tungsten powder as a contrast agent in the polymer flow. The study successfully visualized a parabolic velocity profile, demonstrating the method’s efficacy.
