As a designing technique,blade sweep is currently widely utilized in the design of axial fans/compressors.The flow mechanisms of blade sweep has been extensively studied.In recent years,many studies have reported the incidence variation due to sweep,which can be attributed to the alteration of inlet radial equilibrium and axial velocity distributions induced by blade sweep.An inlet flow model of swept blades for streamline curvature through-flow methods is developed.The model takes into account the variatio...
