Description
Fly Ash Cyclone Project Description
In this project, Ansys Fluent software has simulated the motion of particles in a Fly Ash Cyclone CFD Simulation. We used the one-way DPM to simulate the discrete phase. A cyclone is a device used to separate particles from gas and has many applications in industry. The Eulerian-Lagrangian technique is applied in the cyclone separator simulation. In this approach, the gas is treated as a continuum, and Lagrangian tracking tracks individual solid particles through the flow field to determine their position. In cyclone separators, the drag and gravity forces are considered significant due to the large ratio of the gas-particle density.
Cyclone
A Cyclone separator is a particulate control system used in industries to control the particulate emissions to the atmosphere. Cyclones are efficient, cost-effective, and consume low energy. The cyclone separator separates particles of different sizes from gas by centrifugal force. The design of cyclones is a little complex, but its high separation efficiency compensates for it. Cyclones are centrifugal separators consisting of a barrel (the upper chamber) where separation occurs and a cone (the lower section) where collection takes place.
The flow field and performance of the cyclone separator are affected by gas-solid interactions inside the cyclone. The presence of particles does not affect the flow field due to small particle loading in the cyclone, and coupling of the particle effect in-stream is considered significant. The basic principle of separation is that the particles with higher densities have higher inertia, and hence they tend to revolve in a larger radius. The heavier particles spin near the wall where they slide down, and the lighter particles rotate near the center and are collected out of the cyclone at the top.
Geometry & Mesh
The 3D geometry of this project has been produced with SpaceClaim software.
Mesh is created with Ansys meshing software, and the mesh type is unstructured. The number of cells is 1028959.

Fly Ash Cyclone Results
At the end of this simulation, The motion of the particle inside the cyclone was investigated. Particle velocity, pressure, and air gas flow counters were also examined. It was also observed that lighter and heavier particles separate due to centrifugal force and gravity. It is observed that most of the particles entering from the inlet exit from the lower outlet and air also leaves the upper outlet, and a small number of particles are trapped in the upper part of the cyclone.

Mr. Raven Runte Jr. –
The Fly Ash Cyclone simulation sounds very detailed and comprehensive. What kind of validations have been done to ensure the accuracy of the CFD results with actual physical performances of cyclones?
MR CFD Support –
The accuracy of any CFD simulation results is closely checked by conducting a validation study. This involves comparing the numerical prediction data with available experimental data or with empirical correlations established by industry standards. For the Fly Ash Cyclone simulation, validation would involve checking particle separation efficiencies and flow field predictions against data from well-characterized cyclone models or actual performance metrics from operational cyclones. Specific methodologies for validation may include cross-checking pressure drop predictions, particle cut size determinations, and overall efficiency ratings.
Chloe Upton –
This sounds incredibly sophisticated. Could you please clarify if the impact of different particle sizes was accounted for in the simulation?
MR CFD Support –
In the simulation of the Fly Ash Cyclone using Ansys Fluent, the effect of different particle sizes on the cyclone separator’s performance is indeed considered. The DPM (Discrete Phase Model) enables us to track a range of particle sizes and their behavior within the cyclonic flow, capturing the dependency of centrifugal and gravity forces on particle size. This feature is crucial to accurately simulate the particle separation process within the cyclone.

Sean Kerluke –
I noticed that the simulation uses the one-way DPM model. Can you explain when it is appropriate to use a one-way DPM instead of a two-way or four-way coupling in particle-laden flows?
MR CFD Support –
The one-way DPM (Discrete Phase Model) can be appropriately used when the particle concentration in the flow is so low that the particles do not significantly affect the continuous phase fluid flow and, therefore, the fluid’s impact on the particles needs to be considered, but not vice versa. This approach simplifies the simulation and allows for less computational cost while still providing satisfactory results for the specific conditions where particle interactions with the fluid are much more significant than interactions among particles or feedback effects on the fluid. However, for higher particle loadings where the interactions between the particles, as well as with the continuous phase, become significant, two-way or even four-way coupling may be required for an accurate simulation.

Miss Etha Armstrong –
The detail on particle separation is fascinating. Do the results show what size particles remain trapped in the upper part of the cyclone?
MR CFD Support –
In a cyclone simulation such as this, particles are typically separated based on their size, with larger and heavier particles moving towards the outer edges and smaller, lighter particles remaining closer to the center due to lower centrifugal force acting on them. The size of particles that remain trapped in the upper part of the cyclone would be smaller and lighter compared to those that exit from the lower outlet. For specific size-related data, you would need to refer to the results, which will provide detailed insights into the distribution of particle sizes and where they end up within the cyclone separator.

Florian Hammes II –
This training sounds comprehensive, but I’m curious which factors can affect the separation efficiency of the cyclone the most and how they were addressed in this simulation.
MR CFD Support –
The separation efficiency of a cyclone is most significantly affected by factors such as particle size and density, inlet velocity, cyclone design (e.g., diameter, height, cone angle), and operational variables like gas flow rate. In this simulation, the gravity effect on particles, centripetal forces due to rotation, and drag forces acting on the particles were carefully considered as part of the Eulerian-Lagrangian technique to ensure accurate tracking and separation. Additionally, various boundary conditions and solution methods, like the Reynolds stress model for accounting for flows with high levels of swirl and recirculation inside the cyclone, supported capturing these effects adequately in the performance prediction of the cyclone separator.
