Abstract

<p>In order to maintain the outer diameter without increasing the number of stages of the fan at a given outer diameter and rotational speed of the axial fan, the theoretical analysis and CFD analysis of the fan with conical hub are carried out. Theoretical analysis confirmed that the fan of this configuration can increase the pressure compared to the conventional fan of the same size (With a cylindrical boss) and compared with CFD analysis results. To further increase the pressure of the fan, a pilot and a rectifier vane were planned on the runner with a conical hub, and theoretical and CFD analyses were carried out for each case. According to the results, the runner with guide vanes and conical hubs and the rectifier vanes were designed, the axial fan with conical hubs and guide and rectifier vanes was constructed, and the characteristics of this axial fan were confirmed by CFD analysis. The results showed that this axial fan has a relatively wide stability zone near the operating point with a pressure of 710 Pa (28.77%) and an efficiency of 5.6% higher than the conventional axial fan.<br></p>
