Design optimization of a low-speed
fan blade with sweep and lean
Abstract:The present work performs numerical optimization for design of blade stacking line
for an axial flow fan with response surface method using three-dimensional Navier–Stokes
analysis,and evaluates the effects of sweep and lean on the performance of the fan blade.Reynolds-
averaged Navier–Stokes equations are discretized with finite-volume approximations
using unstructured grids.Four geometric variables concerning spanwise distributions of
sweep and lean of blade stacking line are chosen as design variables to find maximum efficiency.
The computational results show good agreements with experimental data.The total efficiency
is successfully increased in comparison with the reference fan by optimizing threedimensional
stacking line with sweep and lean.Coupling of sweep and lean also improves
