Numerical and experimental investigation of flow loss and flow structure of circular arc cambered plate blade cascade

Abstract: Due to the low production cost, circular arc blades are often applied to axial fans as outlet guide vane. At present, there is less available information focusing on the flow loss and flow structure of circular arc blades in the open literature. In particular, the influence of leading edge and trailing geometries on the aerodynamic performance of circular arc blades remains unknown. In this study, the circular arc blades edge with different leading edge and trailing edge are investigated and compared with nume… Show more

“…The velocity of inflow is smaller than Mach number 0.3, so the flow is considered as incompressible (ρ is consistent). The turbulent intensity is set as 2%, which is tested in the wind tunnel in our lab [27,28]. The turbulent length is set as 0.0367 m [28].…”

“…The fences with large height produce additional flow loss due to the reverse flow between the fences and the flow on the endwall behind the fences. Splitter [22][23][24] Reduce the end-wall loss from the mixing out of secondary flow vortices.…”
