The aim of this paper is to present an extension of the original non-intrusive radioactive
particle tracking method (RPT) to any geometries with irregular moving boundaries. The …

One aspect that must be addressed when designing tumbling blenders is poor axial mixing,
which can lead to non-homogeneous mixtures, especially when the particle physical and …

Determining and controlling the trajectory of solid flocs in a settler are of paramount
importance to ensure the desired solid–liquid separation. This work evinces the feasibility of …

Radioactive particle tracking (RPT) is one of the most widely used non‐intrusive velocimetry
technique for multiphase reactors. The large volume of interrogation and the presence of …

Radioactive particle tracking is a nonintrusive technique that has been successfully used to
study the flow dynamics in a wide range of reactors and blenders. However, it is still limited …

Circulating fluidized bed (CFB) is used for a wide range of gas–solid reactions. However,
most of the data reported on CFBs are for Geldart's group A particles, although the …

Gas–solids fluidization finds extensive application in com-bustion, gasification, granulation,
polymerization, drying, and many other industrial applications. In almost all these …

Radiotracer techniques are widely used for troubleshooting and detection of pathological
flows in industrial reactors. In recent decades, there has been a trend towards using …

Local and macroscopic solids flow structure and kinematics in a 3‐D gas–liquid–solid
fluidized bed were studied using a noninvasive radioactive‐particle tracking (RPT) …

Solids movement in a gas-solid fluidized bed was monitored by a Radioactive Particle
Tracking (RPT) technique. The gas was air at room temperature and atmospheric pressure …
