The experimental investigation was conducted in a low speed annular wind tunnel.The energy loss evolution from the upstream to the downstream in the blade cascade channel with aft-loaded profiles was measured in detail.The results of the present study showed that energy loss occurs mainly in the places near the leading and the trailing edges.Therefore
the measures to be taken are to choose the leading edge diameter
to match the portion of adverse pressure gradient zone with its value and to improve the static pressure distribution along span height.
