Abstract: The areas where the supply of grid power is very difficult cross flow turbines (CFT) are used for low head power production. Results are presented for optimum profile of the leading edges of blade. Four different profiles (flat tip blade profile, round tip blade profile, pointed tip blade profile and oval tip blade profile) are modelled and simulated with ANSYS CFX and then compared their performance in terms of their efficiencies. The complete turbine is analysed for the determination of the leading edge of the blade in the first stage and the trailing edge in the second stage. The design and simulation conditions are based on the installed CFT at Chitral City of Pakistan. The results show that efficiency of the round tip blade profile is better than the other three profiles of the blade.
