Abstract :
In this study, CFD simulations are utilized to perform flow visualization, torque calculation, efficiency estimation, and noise analysis. For demonstration purpose, an 80 mm-diameter backward-inclined (BI) centrifugal fan is chosen to serve as the research subject. The result indicates that the P-Q curve and the sound pressure level (SPL) spectrum of the experiment are in agreement with those of numerical calculations. In summary, this research establishes an integrated aerodynamic, acoustic, and electro-mechanical evaluation approach that can be used as an important tool for fan designers.
