The purpose is to investigate the airflow characteristics inside the centrifugal fan.
Moving Boundary: The internal airflow analysis of the centrifugal fan aims to investigate the airflow characteristics within the fan by modeling the basic shape of the centrifugal fan and applying moving boundary conditions to the blades. The centrifugal fan is a multi-blade fan with forward-curved blades, and its characteristics involve many factors such as the shape of the blades, the number of blades, and the shape of the casing.

basic information
【Analysis】 ○ Modeling of the components of the centrifugal fan, including the blades and casing ○ Number of blades = 16, Diameter = 500mm, Casing diameter = 800mm ○ Total number of grid points in the model is 161 (X) × 130 (Y) × 55 (Z) = 1,151,150 【Analysis Results】 ○ Increase the fan's rotational speed over time and observe the airflow ○ A swirling flow occurs as the blades rotate ○ At the outer circumference of the blades, the flow moves towards the outlet, and simultaneously, a flow from inside the blades through the gaps towards the outer circumference is generated ○ It is understandable that the pressure distribution is high at the outer circumference of the blades and low inside ○ By using the moving boundary function, airflow analysis of machines with rotating parts, such as fans, is also possible ● For more details, please contact us or download the catalog.
