Announcements Advanced Design Technology will host Optimum Loading for Axial Fans in two sessions on October 17th and again on the 18th.

This one hour educational webinar will present the results of an industry wide study aimed at identifying generally applicable design guidelines for the design of high efficiency and low noise axial fans.

Sponsor CFD Review

The study, sponsored by 16 fan manufacturers and supported by 6 universities and research institutes, included a large parametric study of the main parameters for axial fans design such as blade loading distributions, vortex patterns and stacking conditions (sweep angles).

Initially 22 different designs were generated and analysed in coarse-mesh CFD, 14 were then experimentally tested in an anechoic chamber and finally 6 designs were selected for detailed fine-mesh CFD analysis.

The presentation will provide detailed review of numerical and experimental results highlighting:

  • Analysis of different Vortex structures;
  • Identification of limiting streamlines and effects from tip leakage vortex formation;
  • Examination of total pressure loss coefficients.

The webinar will conclude by presenting an optimum loading configuration for systematic design of high efficiency and low noise axial fans.
