Cyclone CFD Simulation
Cyclones are one of the most widely used industrial systems in the field of air dewatering or separation of solid particles from gas flow. In such systems, the operation of separating solid particles from gaseous flow is performed by centrifugal and gravity forces without the use of filters.In addition to reducing air pollution, cyclones are also used to restore solid particles to the production cycle.
This product includes a CFD simulation and training files using ANSYS Fluent software.
There are some free products to check the service quality.
There are one inlet and two outlets for solid particles and pure air in cyclones. The air containing particles enters the cyclone from the inlet of the cyclone and moves in the space between the inner cylinder and the outer cylindrical body in a spiral and vortex manner, such that the solid particles suspend. Due to the centrifugal force and heavier weight, particles separate from the gas stream and move downward due to gravitational force. In this way, the solid particles in the air separate from the air flow. The gaseous flow also flows upward and reaches the upper part of the chamber after reaching the conical region.
Geometry & Mesh for Cyclone CFD Simulation
Gambit (or Design Modeler) software models the present 3-D geometry. The cyclone structure consists of a cylindrical part and a partially conical part.
Gambit (or ANSYS Meshing) software grid the present model. The mesh was of an unstructured type and the element number was 142499.
In the present simulation, we define air as gas flow (continuous phase) and ash as solid particles (discrete phase).
To solve this problem, we consider several assumptions:
– Simulation is steady.
– Gravity effect is equal to 9.81 m.s-1.
– The solution is pressure-based.
Discrete Phase Definition
This simulation examines the behavior of a discrete phase from a Lagrangian perspective in the presence of a continuous fluid in the Eulerian perspective. The gas flow as a continuous fluid is under the Eulerian view, while the ash particles are discretized and Lagrangian. The assumption is that the continuous phase does not affect the discrete phase behavior. Therefore, we disable the Interaction With Continuous Phase for the discrete phase setting. We also define the discrete phase injection as the INERT of the cyclone inlet, meaning that the discrete phase is ineffective and does not exhibit specific behavior.
All files, including Geometry, Mesh, Case & Data, are available in Simulation File. By the way, Training File presents how to solve the problem and extract all desired results.
