Description
Description
This simulation is about a Centrifugal Blower via ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
The blower is a device for blowing high-pressure air, which generally has applications such as dust cleaning. For example, a blower is used to clean computer parts and equipment.
With its rotational motion, the central motor of this device creates high pressure in the air and directs this high-pressure air out of the device’s outlet. The blower designed in this modeling is centrifugal.
The centrifugal blower can absorb air from its central part, and then this airflow enters the central impellers in the form of a fin disc. The rotational motion of the blades at high speed causes the airflow to rotate.
The centrifugal force increases the air pressure and, consequently, the airflow’s velocity. Finally, this high-pressure air is directed to the outside environment through a duct installed on the blower’s outer body.
The present model is designed in two dimensions using Design Modeler software. The model is a two-dimensional centrifugal blower designed to reduce computational costs. Since the blower is centrifugal, the current input is from the model’s center, and its output is located in the model perimeter.
The model is then meshed by ANSYS Meshing software. The model mesh is unstructured, and 172824 cells have been created.
Centrifugal Blower Method
In this simulation, a zone around the blades is distinguished from the entire computational domain to define the rotational flow of air. The Frame Motion has been used for this zone in cell zone conditions.
Doing so assumes that instead of defining rotational motion for the blades at a given speed, rotational flow is defined for the air around the blades at the same speed. This rotational motion has a rotational speed of 260 rad/s.
Also, since the model’s prominent nature is related to pressure changes, the pressure boundary condition is used at the input (central part of the model) and the output (outer part of the model).
Centrifugal Blower Conclusion
After simulation, two-dimensional contours of pressure, velocity, and turbulence kinetic energy are obtained. Also, two-dimensional pathlines and two-dimensional velocity vectors are obtained.
The results show that the airflow enters the blower’s central part and experiences high-pressure rotational motion in the areas adjacent to the blades. Then the pressure and speed of the airflow increase and are directed outwards from the blower outlet.

I am very impressed with the level of detail in the Centrifugal Blower CFD Simulation tutorial. As someone interested in blower design, this simulation provided insightful data. I’m curious, though, how the software dealt with the transition from the rotating frame of reference in the blade area to the stationary environment. Was it smooth or iterative, and how was this managed within the simulation?
MR CFD Support –
The transition from the rotating frame of reference around the blades to the stationary environment is managed smoothly in ANSYS Fluent through the use of a Multiple Reference Frame (MRF) or sliding mesh model. In the MRF approach, which is likely employed here given the steady-state nature indicated in your description, the software treats the rotating and non-rotating regions as separate but connected, allowing it to calculate the effect of the rotating blades on the stationary parts. This allows Fluent to simulate the rotational flow without physically rotating the mesh, resulting in Fluent iteratively finding a solution that reflects the interactions between the two reference frames.

The pressure levels achieved by the centrifugal blower wasn’t mentioned in the description. Can you share what pressures we’re talking about here?
MR CFD Support –
In this centrifugal blower simulation, the pressure levels are scenario-specific and depend heavily upon the rotational speed, blade design, and other operational parameters. While I don’t have exact figures from the specific simulation, typical results would include the distribution of static and dynamic pressure within the blower, highlighting regions of high and low pressure generated by the blower’s operation.

What kinds of results are observed from the pressure and velocity contours in this Centrifugal Blower simulation?
MR CFD Support –
In the Centrifugal Blower simulation, pressure and velocity contours reveal how efficiently the device elevates air pressure and velocity. Specifically, more uniform and higher pressure readings near the blower’s output likely indicate effective performance. Conversely, abrupt changes could signal inefficiencies or potentially problematic areas within the blower’s design.

Lavada Pollich –
Is it necessary to simulate the actual rotational movement of the blades, or is the frame motion approach in ANSYS Fluent software enough to capture the air flow accurately in the centrifugal blower?
MR CFD Support –
In many cases, using the frame motion approach to simulate the rotating zone is enough to capture the airflow behavior accurately without having to model the actual rotation of the blower blades. It simplifies the calculations, reducing computational costs while still reflecting realistic performance characteristics of a centrifugal blower in the simulation.
