Abstract Radioactive Particle Tracking (RPT) is a non-invasive measurement technique
used to reconstruct the Lagrangian particle field inside a fluid flow. This technique tracks the …

Bubble column dynamics can be properly studied with advanced velocimetry techniques,
like radioactive particle tracking (RPT). However, sophisticated methods are scarcely used …

The contact time of particles at the walls of gas fluidized beds has been studied using a
radioactive particle tracking technique to monitor the position of a radioactive tracer. The …

One problem associated with the use of Computational Fluid Dynamics (CFD) in reactor
modeling is the proper validation of the models. Proper validation in this context means that …

Radioactive particle tracking technique (RPT) has proven to be a powerful and versatile
technique both in terms of the richness of information it provides as well as the variety of …

In this work, the characteristics of two-phase oil-water flow through a coiled tube geometry
have been investigated. Radial mixing, local volume fractions, and phase holdup, over a …

The proposed tracking method describes the trajectory of a radioactive particle moving in a
fluid as a sequence of small cubic cells occupied by successive particle positions. In …

This work provides a detailed study on the agitation rate influence on the solid motion within
a pilot-scale slurry tank containing nickel oxide particle agglomerates suspended in iso …

The variation of the particle–wall friction factor along the riser is investigated in an Internal
Circulating Fluidized Bed (ICFB) riser 1 m in length and 0.052 m in diameter. The results …

A fundamental understanding of hydrodynamics is critical to the design and scale-up of
bubble column reactors. Towards this goal, systematic experimental and theoretical …
