  • Study was carried out using the combination of numerical simulation and cascade experiment to understand the effects on flow loss from loading distribution design and non-smooth profile design based on two-dimension span-wise groove combined with loading distribution design. Research shows that fore-loaded design is superior to aft-loaded design in two-dimension aerodynamic performance under low Reynolds number conditions; non-smooth profile design based on two-dimension span-wise groove can improve aerodynamic performance at low Reynolds number, and decrease it at high Reynolds number; non-smooth profile design based on two-dimension span-wise groove combined with aft-loaded design can improve aerodynamic performance in wider range of Reynolds number.
