The purpose is to investigate the airflow characteristics inside the blower fan.
Moving Boundary: The internal airflow analysis of the Sirocco fan aims to investigate the airflow characteristics within the Sirocco fan by modeling the basic shape of the fan and applying moving boundary conditions to the blades. The Sirocco fan is a centrifugal 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 toward the outlet, and simultaneously, a flow from inside the blades through the gaps to the outer circumference is generated ○ By examining the pressure distribution, it can be understood that the pressure 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.

Company information
In environmental simulation, we develop and sell proprietary 3D fluid analysis programs and provide contract analysis services using these software tools. For over a decade, we have been engaged in thermal fluid analysis in fields such as architecture, civil engineering, machinery, and electronics, handling numerous analyses and accumulating a wealth of know-how and knowledge. Our diverse analysis and visualization functions, honed through practical experience, have received high praise as CFD software from many companies and research institutions. ● Import functionality for BIM-compatible CAD data such as Revit and DXF ● Map information (GIS) data import functionality ● SuperCartesian functionality that freely represents diagonal boundaries and complex curved surfaces ● High-speed, high-precision radiation calculations and high-precision turbulence analysis using DNS ● Moving boundary problem analysis functionality that accommodates the movement of multiple objects in space ● User-friendly interface and easy-to-understand animation features In addition to software support, we also accept contract analyses. Focusing on air conditioning ventilation and wind environment analysis, we provide high cost-performance solutions for a wide range of problems, from simple, small-scale issues to complex, large-scale analyses. We look forward to your visit, along with our abundant analysis case studies.
