Bubble characterization in a fluidized bed by means of optical probes
The objective of this paper is to show and discuss the applicability of optical probes to measure the bubble size and bubble rise velocity in fluidized beds.
Downer Reactor Flow Measurements using CREC-GS-Optiprobes
This study describes the potential intrusive effects of CREC-GS-Optiprobes on the flow pattern in gas–solid downflow units by calculating granular flows and their interactions with the CREC-GS-Optiprobes using a CPFD (Computational Particle Fluid Dynamic) numerical scheme in three dimensions.
Advanced Computational Modeling of Proppant Settling in Water Fractures for Shale Gas Production
This paper by Kuochen Tsai, Ernesto Rafael Fonseca, Sujatha Degaleesan, and Ed Lake from Shell shows advances in the numerical simulation of proppant transport in hydraulically stimulated fractures for oil and gas production.
Reverse core-annular flow of Geldart Group B particles in risers
Experiments involving monodisperse Geldart Group B particles were carried out in a pilot-scale riser of a circulating fluidized bed, and several combinations of superficial gas velocity, solid flux, average particle diameter, and particle material density were investigated
Cluster characteristics of continuous size distributions and binary mixtures of Group B particles in dilute riser flow
Gas–solids circulating fluidized bed (CFB) experiments have been carried out, with a focus on understanding the impact of polydispersity on cluster characteristics in a dilute riser.
