Effect of Forward Sweep on the Performance of an Axial Blower
Abstract:
Effects of changing the blade sweep without redesigning the datum blade sections are studied on the pressure rise, efficiency and 3D flow field of an axial blower. Four forward swept blade configurations (5°, 10°, 15° and 20°) are compared with an unswept blade. RANS and URANS simulations are carried out for the aerodynamic performance analysis and 3D flow field behaviour. Results indicated higher pressure rise and wider stall margin thus improved efficiency with higher forward sweep angles.
