On trajectory and velocity measurements in fluidized beds using positron emission particle tracking (PEPT)

Positron emission particle tracking (PEPT) is a non-invasive technique that can be used for following the trajectories of particles in fluidized beds, so increasing understanding of solids motion in fluidized bed processes. We describe how PEPT is applied, how its performance is optimized, and how trajectory information can be built up into instantaneous and time-averaged measures of particle movement. Choices and pitfalls in data processing are explained and illustrated by reference to the travelling fluidized bed (TFB) collaboration initiated by Professor John Grace.

Automated summary

This article discusses the application of positron emission particle tracking (PEPT) technique in tracking the trajectories of particles in fluidized beds, and how to optimize its performance. It also explains how trajectory information can be transformed into measurements of particle movement and discusses the choices and pitfalls in data processing.
