GEN IV Webinar Series 48: Development of Multiple-Particle Positron Emmision Particle Tracking for Flow Measurement, December 17, 2020, 8:30 a.m. EST

Body

Flows in opaque systems can present a significant challenge to experimental investigators. Understanding flow phenomena in reactor components often relies on the use of simulation, as well as experiments using surrogate materials and fluids to allow optical access. Positron emission particle tracking (PEPT) is a radiotracer-based technique that uses the same technology as the medical imaging platform PET (positron emission tomography). As such, PEPT can be used to directly study flows in opaque systems. The research focus has been on the development and deployment of new PEPT reconstruction algorithms that allow the simultaneous tracking of multiple tracers, increasing data collection efficiency and enabling new measurements. Herein Dr. Wiggins will discuss the basics of PEPT, as well as its utility for measurements in pipes, heat exchangers, and pebble beds, among other systems. The data gleaned from such experiments can be used for both fundamental understanding of flow phenomena and validation of the computational fluid dynamics models being used for next generation reactor design.
