    Abstract
  • It present a numerical method, based on 3-D incompressible steady time-averaged N-S equation and K-ε turbulence model equation, using in aerodynamic designing for high efficient civilian fan. The code was adopted limited volume method and was under the non-orthogonal curve coordinate by means of famous SIMPLE. Through calculating and analyzing, it is proved that the bent-swept blade can control aerodynamic allocation, and has a higher efficiency, a nice flow field with less second flow loss when compared with a straight blade.
