Atmospheric bubbling fluidized bed combustion: Application to high ash coals and approach to scientific research
(1996-06-01)
This work is concerned with research on atmospheric bubbling fluidized bed combustion (AFBC) applied to mineral coals of high ash content. Coals is considered in a scenario of power generation both domestic and world-wide, ...
Comparative 2D and 3D analysis on the hydrodynamics behaviour during biomass gasification in a pilot-scale fluidized bed reactor
(2019-02-01)
2D and 3D simulations were carried out to predict the whole gasification process behaviour in a pilot-scale bubbling fluidized bed reactor. Special concern for the complex hydrodynamics phenomena within the fluidized bed ...
Fluidization of forest biomass-sand mixtures: experimental evaluation of minimum fluidization velocity and CFD modeling
(Taylor & Francis, 2020-07-03)
An experimental fluid-dynamic study of sand-forest biomass mixture fluidization was conducted. Different proportions of biomass/sand were tested. Sawdust from the Abra Ancha sawmill, located in the town of Aluminé, Argentina, ...

Comparing ANSYS Fluent® and OpenFOAM® simulations of Geldart A, B and D bubbling fluidized bed hydrodynamics
(Emerald, 2019-09)
Purpose: The purpose of this study is to assess the performance of ANSYS Fluent® and OpenFOAM®, at their current state of development, to study the relevant bubbling fluidized bed (BFB) characteristics with Geldart A, B ...
Prediction of the combustion process in fluidized bed based on physical-chemical properties of biomass particles and their hydrodynamic behaviors
(Elsevier B.V., 2014-08-01)
The utilization of biomass in fluidized bed reactors is due to alternatives created by the carbon credit market and to environmental concerns. This fact calls for an accurate determination of physical-chemical properties ...
Fluidized bed drying of blackberry wastes: Drying kinetics, particle characterization and nutritional value of the obtained granular solids
(Elsevier Science SA, 2021-06)
Particulate systems for functional ingredient development were obtained by fluidized bed drying of blackberry wastes. Fluidization behavior, drying characteristics, and physicochemical and functional properties were studied ...
Three-fiber optical probe for studying fluidized gas-solid beds in bubbling regime.
(Universidad Nacional de Colombia Sede Medellín. Facultad de Minas, 2011)
This work shows the development of a three-optical fi ber probe to study the behavior of the bubble in bubbling fluidized gas-solid beds. Its compact design allows minimizing disturbance to the fl ow fi eld, resulting in ...
Assessment of gas-particle flow models for pseudo-2D fluidized bed applications
(Taylor & Francis, 2018-04)
The aim of this work is to provide more insight into the general modeling criteria for simulating pseudo-2D bubbling fluidized beds. For this purpose, two experimental-based problems are studied. First, a fluidized bed ...
