Fluid dynamic study of mixtures of sugarcane bagasse and sand particles: Minimum fluidization velocity
(2017-01-01)
This paper is focused on the study of fluid-dynamic behavior of mixtures of the sugarcane bagasse particles and quartz sand in a transparent fluidized bed column. The minimum fluidization velocity (Vmf) was determined by ...
Fluidization of biomass: a correlation to assess the minimum fluidization velocity considering the influence of the sphericity factor
(Taylor & Francis, 2021-01)
This paper deals with the influence of different definitions for evaluating the sphericity factor on the prediction of minimum fluidization velocity (U mf) of different agro-industrial/forestry biomass residues and sand. ...
Caracterização da fluidização de biomassas de casca de madeiras em leitos polidispersos
(Universidade do Vale do Rio dos Sinos, 2015-11-20)
This paper presents the physical characterization of samples of biomass and inert and the characterization of fluid dynamics of binary mixtures of sand and biomass, by determining the fluidization curves from these mixtures. ...

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, ...
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 ...
Single-Bubble Dynamics in a Dense Phase Fluidized Sand Bed Biomass Gasification Environment
(ACS Publications, 2020)
Biomass gasification in fluidized beds is a process of important commercial value. The simulation of these fluidized bed units strongly depends on establishing bubble dynamics in dense phase sand fluidized beds. In these ...
