Numerical analysis of gas distribution in fluidized beds



The objectives of this CFD Design project are to improve the performance of fluidized bed drying using different ideas such as new designs of the distribution plate and gas chamber, by modifying the gas injection system or by using intermittency. The goal is to carry out a numerical study to understand the effect of various operating parameters and geometric changes. The numerical CFD simulations will be carried out using ANSYS Fluent V18.2. ;


The Gas distribution of the fluidized bed column is simulated in stages. First, the gas chamber and the gas distributor are simulated together for a single-phase i.e., air as an inlet fluid.
The single and multi-phase flow theories used for the current CFD simulations using ANSYS Fluent V18.2, Transient flow, drag model applied, group B particle of 275-micron diameter is used, grid independence test is carried out to understand the effects of grid sizing ;

Outcome/Conclusion –

In this research, several gas distribution systems with various gas distributor designs were proposed. Their performance in terms of the uniformity of gas distribution at the exit of orifice holes of the gas distributor was examined with the use of computational fluid dynamic analysis. The CFD simulations were carried out in ANSYS FLUENT v18.1 and 18.2 using single and multiphase models. The base case design of gas distributor with a uniform percentage open area showed the non-uniform distribution of gas. Hence, the distributor geometries with different percentage open area (for circular pattern and triangular pitch arrangement), type of gas entry were used to understand if the quality of fluidization can be improved. It was observed that the non-uniformity of gas distribution of circular pattern increases as the percentage open area is increased from 15 to 20; however, the gas distribution again improved for 25% open area, we would like to check this behavior again. On the other hand, for the triangular pitch arrangement of the orifice holes (which is the most commonly used arrangement in industries), the non-uniformity increases as the percentage open area are increased. The comparison of two patterns of orifice arrangement for the lower open area showed that the triangular pitch arrangement provides a better air distribution. The results also revealed that the non-uniformity in air distribution occurs mainly in the central and middle part of gas distributor for lower open area, while, for the plates with higher percentage open area, the non-uniformity is prominent near the edges of the gas distributor plate. An attempt is made to further improve the uniformity using variable open areas in different regions of the plate. The CFD Simulation results of the variable opening area proved that the new design can generate better gas distribution with a more uniform velocity pattern than the designs discussed earlier, at least for the bottom entry of the gas nozzle. The simulation results also show that the gas distribution is severely affected by a gas nozzle entry position. The results show that the bottom entry position of nozzle provides uniform distribution, while the side entry results in severe non-uniformity in gas distribution.
The two-phase fluidized bed FSI simulations were also carried out to analyze the particle behavior in the presence of gas distributor with varying percentage open area and different gas inlet entry. The Eulerian-Eulerian approach is incorporated in the two-phase CFD simulation with a constant volume fraction. The CFD FSI Analysis results showed that the particles gradually start fluidizing at lower flow time, as the flow time increases the bed expands, and the fast fluidization is observed, eventually the particle fall back in the bed. The higher percentage of open area showed a turbulent regime. For the fluidized bed with side entry, the results showed that the particles start fluidizing on the side of the chamber opposite to the entry position. In general, lower percentage open area and bottom entry of the gas nozzle should be preferred. The other parameters used were the optimized parameters from the previous work. However, more detailed two-phase CFD simulations should be carried out to further analyze the use of the variable open area for uniform fluidization.

CFD Analysis of Arterial Blood Filter


The Arterial Blood Filter (ABF) is used to remove the air bubbles of size greater than 40 microns. Due to tangential circular flow inside the ABF the air bubble experience lesser centrifugal force and can be removed from the top of the filter. This kind of flow causes some pressure drop. This action is simulated for different flow rates.
The fluid domain of the ABF component is extracted for this Blood Flow CFD Simulation. The filter is complex geometry and it is replaced with porous media. The Darcy and Forchheimer coefficients are calculated and gave as an input to the porous media. This will provide the same resistance provided by the filter. This analysis is carried out for other flow rates as well.
It is observed that the pressure drop increases with the flow rate. The pressure drop is measured using probes across the filter.

CFD Aerodynamic Optimization of bi-directional flow turbine



Aerodynamic performance enhancement of bi-directional flow turbine using Gurney flap and analysis using OpenFOAM CFD Software

Numerical Methodology

Design parameter: Gurney flap (0.5 to 3% Chord)
CAD Modeller: Solidworks 2015.
Grid generator: Ansys ICEM CFD 15.0.
Solver: OpenFOAM 4.0.
Post-processor: ParaView 5.5.2.
Wells turbine is a bi-directional flow turbine used in the oscillating water column (OWC) to harvest wave energy. The Wind Simulation Study consists of symmetrical blades and provides uni-directional torque for the oscillating airflow inside the OWC. A Gurney flap concept was introduced in both the pressure and suction side of the Wells turbine to retain the blade symmetry. The flap height was varied from 0.5% to 3% chord length and the performance characteristics were computed by solving 3D steady incompressible Reynolds-averaged Navier-Stokes equations using OpenFOAM.
The reference geometry of the Wells turbine was taken from the works of Toressi et al. (2008). A single blade with the periodic interface was chosen as a computational flow domain to reduce computational time and power. The flow domain was modeled using Solidworks, and Solid Edge and exported as.STEP file.
Later, the grid generated using Ansys ICEM CFD and exported in .msh format. It was used as input for OpenFOAM analysis. Grid convergence index was calculated to assess the numerical uncertainty and the present numerical results were compared with experimental and numerical results available in the open literature. The post-processing figures were obtained using ParaView to understand the fluid dynamics behind performance improvement.


  1. The Gurney flap increased blade loading and the torque produced.
  2. A pair of counter-rotating vortex was generated behind the trailing edge that modified the trailing edge Kutta condition which increased circulation and lifts. At a higher angle of attack, the counter-rotating vortex pair collapsed, and the aerodynamic benefit of the flap was diminished.
  3. A flap of 0.5% chord length enhanced the relative average torque produced by 10.7% with a decrement in relative average efficiency by 4.7% before stall condition.
  4. A flap height greater than 1.5% chord length advanced the stall and reduced the operating range.
  5. The above results from the Wind Load Analysis are published in the peer-reviewed journal “Ocean Engineering”.
