Abstract and Figures

An Eulerian-Lagrangian approach is developed within the OpenFOAM framework to investigate the effects of three well-known inter-phase drag force correlations on the fluidization behavior in a bubbling fluidized bed reactor. The results show a strong dependency on the restitution coefficient and the friction coefficient and no occurrence of bubbling and slugging for the ideal-collision case. The mean pressure drops predicted by the three models agree quite well with each other.

... This approach has been much utilized for simulating coal-powered combustion systems, but less published work is to be found for biomass reactors. However, recent model developments have proven promising with good correlations to experimental work on fluidized bed bioreactors [18]. However, a significant challenge arises when such multi-phase flow simulations are combined with realistic and comprehensive kinetic models as described above. ...

The correlations taken into consideration in the process of developing our own equation for char specific heat modeling belong to Fredlund [18], Koufopanos et al. [11], Gupta et al. [15], and Gronli [17]. ...
A Mathematical Model of Biomass Combustion Physical and Chemical Processes

  • Nov 2020
The numerical simulation of biomass combustion requires a model that must contain, on one hand, sub-models for biomass conversion to primary products, which involves calculations for heat transfer, biomass decomposition rate, product fractions, chemical composition, and material properties, and on the other hand, sub-models for volatile products transport inside and outside of the biomass particle, their combustion, and the char reduction/oxidation. Creating such a complete mathematical model is particularly challenging; therefore, the present study proposes a versatile alternative-an originally formulated generalized 3D biomass decomposition model designed to be efficiently integrated with existing CFD technology. The biomass decomposition model provides the chemical composition and mixture fractions of volatile products and char at the cell level, while the heat transfer, species transport, and chemical reaction calculations are to be handled by the CFD software. The combustion model has two separate units: the static modeling that produces a macro function returning source/sink terms and local material properties, and the dynamic modeling that tightly couples the first unit output with the CFD environment independently of the initial biomass composition, using main component fractions as initial data. This article introduces the generalized 3D biomass decomposition model formulation and some aspects related to the CFD framework implementation, while the numerical modeling and testing shall be presented in a second article.

... As an open source CFD software, OpenFOAM is written by Cþþ, and has been applied to numerical simulation of gas-solid flow in fluidized bed. 18,19 However, a few researchers have used this software to simulate the gas-solid flow of fibrous media except Mead-Hunter et al. 20 Mead-Hunter et al. simulated the gas-liquid flow of the fibrous media for the first time using OpenFOAM, and they simulated the movement of droplets, such as aerosol droplet capture, coalescence, film break-up and the motion of coalesced liquid droplets. ...
Numerical simulation of gas-solid flow characteristic of particles in fibrous media using OpenFOAM
Article
  • Jul 2019
Euler-Lagrangian numerical simulation framework of gas-solid two-phase flow was used to simulate the gas-solid flow characteristic in fibrous media using OpenFOAM in this study. The simulation results were compared with the empirical model and CFD-DEM method. In addition, the deposition morphology of particles, pressure differential and filtration efficiency in unsteady stage and simulation cost were also analysed with OpenFOAM. The results show that OpenFOAM can simulate the process of gas-solid two-phase flow in the fibrous media, and the particles are agglomerated on the surface of fibrous media and form a dendritic structure similar to the experimental observation. The pressure differential in unsteady stage would increase with the mass per unit area. The filtration efficiency would increase with a corresponding increase in the amount of deposition, but the growth rate would decline gradually. Compared with CFD-DEM method, the simulation accuracy with OpenFOAM is slightly lower, especially in the case of large the Stokes number, but the simulation cost is low, too. Therefore, it is necessary to choose one of the two methods according to the actual situation.

Numerical study to invistigate the effect of inlet gas velocity and Reynolds number on bubble formation in a viscous liquid
Article
Full-text available
  • Jan 2015
Bubble formation dynamics has great value in mineral recovery and the oil industry. In this paper, a single bubble formation process through an orifice in a rectangle domain is modelled to study the bubble formation characteristics using the volume of fluid with the continuum surface force method. The effect of gas inlet velocities, Ug similar to 0.1-0.3 m/s on bubble formation stages (i. e., expansion, elongation, and pinch off), bubble contact angle, dynamics and static pressure, bubble departure diameter etc. was investigated through an orifice diameter of 1 mm. The method was also used to study the effect of Reynolds number, Re-mu similar to 1.32-120 on bubble formation when all other parameters were kept constant. It is found that a high inlet gas velocity accelerated the reducing of the bubble contact angle from an obtuse angle to an acute angle and the faster development of hemispherical shape of the bubble. It is also found that an increasing of Reynolds number caused speeding up of the bubble pinch-off and formed a smaller bubble neck height due to stronger vortex ring around the bubble neck.

A two dimensional Euler–Lagrangian model of wood gasification in a charcoal bed—Part II: Parameter influence and comparison
Article
  • May 2017
  • PARTICUOLOGY
A Euler-Lagrangian simulation was employed for a comprehensive parameter study of wood gasification in a fluidized charcoal bed. The parameters that were varied include the initial bed temperature, fuel mass flow rate, inert tar fraction, and kinetic energy losses caused by particle-particle and particle-wall collisions. The results of each parameter variation are compared with a base scenario, previously described in detail in Part I of this study (). The results are interpreted by comparing the reactor outlet temperature, averaged particle temperature, overall wood mass, overall charcoal mass, concentrations of several gaseous species, and axial barycenter data for particles obtained with different sets of parameters. The inert tar fraction and fuel mass flow rate are the most sensitive parameter, while the particle-particle and particle-wall contact parameters have only a small impact on the results. Increasing the reactive tar components by 19% almost doubled the amount of reactive tars at the reactor outlet, while decreasing the restitution coefficients of the particle collisions by 0.2 results in higher overall gas production but almost no change in bed height. Herein, our numerical results are discussed in detail while assessing the model restrictions. © 2017 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences.

Influence of drag force correlations on periodic fluidization behavior in Eulerian–Lagrangian simulation of a bubbling fluidized bed
Article
  • May 2013
  • CHEM ENG SCI
In this paper, an Eulerian–Lagrangian approach, in which the gas flow is solved by the volume-averaged Navier–Stokes equation and the motion of individual particles is obtained by directly solving Newton's second law of motion, is developed within the OpenFOAM framework to investigate the effects of three well-known inter-phase drag force correlations (11 and 6 and EHKL, 2006) on the fluidization behavior in a bubbling fluidized bed reactor. The inter-particle and particle–wall collisions are modeled by a soft-sphere model which expresses the contact forces with the use of a spring, dashpot and friction slider. The simulation results are analyzed in terms of particle flow pattern, bed expansion, bed pressure drop and fluctuation frequency. Qualitatively, formation of bubbles and slugs and the process of particle mixing are observed to occur for all the drag models, although the Gidaspow model is found to be most energetic and the Di Felice and EHKL models yield minor difference. The flow behavior also shows a strong dependency on the restitution coefficient e and the friction coefficient μ and no bubbling and slugging occur at all for the ideal-collision case (e=1, μ=0). Quantitatively, the mean pressure drops predicted by the three models agree quite well with each other and the amplitudes of the fluctuations measured by the standard deviation are also comparable. However, a significant difference in fluctuation frequency is found and the Gidaspow model predicts a lowest fluctuation frequency whereas the Di Felice model gets a highest one. Finally, effects of the spring stiffness and the discontinuity in the Gidaspow model are studied. The results show that both mean bed pressure drop and fluctuation frequency slightly decrease as the spring stiffness increases for all the three drag models and no significant differences are observed in the mean bed pressure drop and fluctuation frequency between the Gidaspow model and the linear continuous model.

Discrete element simulation of particle flow in arbitrarily complex geometries
Article
  • Dec 2011
  • CHEM ENG SCI
Conventional simulations of dense particle flows in complex geometries usually involve the use of glued particles to approximate geometric surface. This study is concerned with the development of a robust and accurate algorithm for detecting the interaction between a spherical particle and an arbitrarily complex geometric surface in the framework of soft-sphere discrete element model (DEM) without introducing any assumptions. Numerical experiments specially designed to validate the algorithm shows that the new algorithm can accurately predict the contact state of a particle with a complex geometric surface. Based on the proposed algorithm, a new solver for simulation of dense particle flows is developed and implemented into an open source computational fluid dynamics (CFD) software package OpenFOAM. The solver is firstly employed to simulate hydrodynamics in a bubble fluidized bed. Numerical results show that a D simulation can predict the bubble size better than a 2D simulation. Subsequently, gas–solid hydrodynamics in an immersed tube fluidized bed is simulated. Results show that bubble coalescence and breakup behavior around the immersed tubes are well captured by the numerical model. In addition, seven different particle flow patterns around the immersed tubes are identified based on the numerical results obtained.

Research on Reducing Erosion by Adding Ribs on the Wall in Particulate Two-Phase Flows
Article
  • Apr 1996
  • WEAR
In the particulate two-phase flow with smooth wall and rib-welding wall, improved κ-ϵ turbulence model and one-way coupling method are employed to compute particle velocities and trajectories, and wall wastage caused by particle impacts. In order to verify the computational results, an apparatus is designed and corresponding experiment is made. Both computational and experimental results show that adding ribs on the wall can reduce wall erosion caused by particle impacts in the particulate two-phase flow. The wall wastage does not vary linearly as rib height. Under a definite rib height, it is most beneficial to reduce erosion when rib width is equal to gap between ribs. For a definite flow, in the region with relative small particle size, the variety of wastage rate changes steeply, whereas particle size exceeds a criterion, the wastage rate changes smoothly. The initial angle of motion direction between particles and gas affects the wall wastage.

A LB-DF/FD method for particle suspensions
Article
  • Jan 2009
In this paper, we propose a lattice Boltzmann (LB) method coupled with a direct-forcing fictitious domain (DF/FD) method for the simulation of particle suspen- sions. This method combines the good features of the LB and the DF/FD methods by using two unrelated meshes, namely, an Eulerian mesh for the flow domain and a Lagrangian mesh for the solid domain, which avoids the re-meshing procedure and does not need to calculate the hydrodynamic forces at each time step. The non-slip boundary condition is enforced by introducing a forcing term into the lattice Boltz- mann equation, which preserves all remarkable advantages of the LBM in simulating fluid flows. The present LB-DF/FD method has been validated by comparing its re- sults with analytical results and previous numerical results for a single circular particle and two circular particles settling under gravity. The interaction between particle and wall, the process of drafting-kissing-tumbling (DKT) of two settling particles will be demonstrated. As a manifestation of the efficiency of the present method, the settling of a large number (128) of circular particles is simulated in an enclosure.

The voidage function for fluid-particle interaction systems
Article
  • Feb 1994
  • INT J MULTIPHAS FLOW
The drag force on a particle in a fluid—multiparticle interaction system may be expressed as the product of the drag force on an unhindered particle, subject to the same volumetric flux of fluid, and a voidage function. It is demonstrated that for a wide varicty of both fixed-bed and.suspended-particle systems, file voidage function may be expressed as ϵ−β, where the exponent β is dependent on the particle Reynolds number but independent of other system variables.
