Unlike conventional fans, the bladeless fan does not produce airflow using moving blades. Instead, it draws air in and amplifies it using fluid dynamics principles and air-multiplier technology. The bladeless fan has several benefits over conventional fans; for instance, It is safer since no moving parts are exposed, particularly in homes with kids and dogs. It is more energy efficient than a conventional fan because it doesn’t require a motor to revolve the blades.

Here is a step-by-step explanation of how a bladeless fan operates. (Note that the explanation is in our simulation design, size, and dimension.)

Air Intake: Four square inlets, each with a side of 21mm, are located in the fan’s base, a cylinder with a diameter of 0.2 meters. These inlets draw The air around them into the fan’s base.

Air Amplification: The air drawn in is forced into the fan’s 0.52 meter-diameter cyclone section. The air is channeled through a ramp with the shape of an airfoil, which causes the air to spiral as it travels and picks up speed. On a flat surface, the air rushes along the airfoil without resistance, but as it crosses over the top, it generates a region of negative pressure, which causes the air to speed up and produce the airlift. A negative pressure region draws in more air and implies it 16 times. Eventually, it achieves completely safe, low-velocity, smooth airflow without blades.

Air Ejection: The high-speed air is discharged through a tiny slit in the fan’s top circular loop. Compared to the choppy air created by traditional fans, this results in a smooth, continuous stream of cooling air.

We modeled the geometry in the design modeler. Then, we meshed the model with ANSYS Meshing software with 1,927,707 cells.


This project uses ANSYS Fluent software to simulate airflow behavior in a bladeless fan. Based on the inlet air flow rate (0.01 m^3/s), the inlet velocity is 5.67m/s.The standard k-epsilon model is used to simulate the turbulence of the flow. Fully turbulent flows are present in the bladeless fan, particularly in the cyclone portion. The k-epsilon model is a suitable fit for this application because it is known to give reasonably accurate predictions in totally turbulent flows.


Simulating the product in ANSYS Fluent resulted in obtaining some contours, vectors, and Pathlines, such as velocity pathlines, which showed how air finds its way to the cyclone flowing over the airflow and pressure and velocity contours presented over the considered planes to show the low-pressure area and velocity distribution.
