This work concerns the development of two new indices that are extensive enough to be
used to assess the mixing efficiency of both granular and fluid flow systems. They are based …

Three-dimensional trajectory time series from a radioactive solid tracer freely moving in a 3-
D conical-base spouted-bed reactor were analyzed using standard statistical and qualitative …

Radioactive particle tracking (RPT) technique is a non‐invasive velocimetry technique,
extensively applied to study hydrodynamics of dense multiphase systems. In this technique …

A recent investigation proposed a simulated radioactive particle tracking (RPT) system using
eight scintillator detectors in order to predict instantaneous positions of a radioactive particle …

We report solids flow pattern in a laboratory-scale fluidized bed of coal and ash mixtures.
Suitable tracers were designed and deployed to determine the solids flow path of a typical …

Slurry bubble column reactors are presently used for a wide range of reactions in both
chemical and biochemical industry. The successful design and scale up of slurry bubble …

The design, performance, and safety analysis of nuclear reactors, in particular boiling water
reactors, requires information about the vapor–liquid flow dynamics. Such data are …

Mixing in monosized particles and binary mixtures of solids in three-phase fluidized beds is
investigated by means of a non-invasive Radioactive Particle Tracking technique (RPT) …

The current work focuses on the hydrodynamic study of liquid-solid mono and binary conical
fluidized bed using the radioactive particle tracking technique. Two different sizes 0.6 and 1 …

The axial motion of HDPE, Acetal, and PTFE spheres immersed in a 3-D bed of the
conventional fluidization materials was studied using the non-invasive radioactive particle …
