Abstract

The paper presents the results of numerical studies of the effects of spinner shape, relative size of hub and the diffuser on the characteristics of axial fans. Obtained the coefficients of of the total pressure, productivity efficiency and power factor.Shows the influence of the spinner shape and relative size of hub on the characteristics of the fans.

Keywords:

axial fan; spinner shape; relative size of hub; the Reynolds-averaged Navier-Stokes equations; coefficients of the total pressure; performance; efficiency; power factor fan
