An axial fan is a type of fan that operates by creating a flow of air along an axis or through the center of the fan. The working principle of an axial fan is based on the aerodynamic principle of axial flow. Here are the basic steps involved in the working principle of an axial fan:
Blade rotation: The axial fan consists of a rotor with blades that rotate around a central hub. When the rotor rotates, it creates a low-pressure area behind the blades, which causes air to be drawn in from the front of the fan.
Airflow: As the air is drawn in by the blades, it is propelled along the axis of the fan. The flow of air is parallel to the axis of the fan, which is why this type of fan is called an axial fan.
Velocity and pressure: The velocity and pressure of the airflow produced by the axial fan depend on the speed of the rotor and the angle of the blades. By adjusting the speed and angle of the blades, it is possible to control the airflow and the pressure generated by the fan.
Overall, the working principle of an axial fan is based on the aerodynamic principle of axial flow, which involves creating a flow of air along an axis or through the center of the fan. Axial fans are widely used in many applications, including ventilation, cooling, and HVAC systems.
