<p>In this study, propeller blade shape suitable for low head and low flow rate condition are investigated by using numerical analysis. The performance of forty-eight blades which are changed three design parameters "specific speed, distance rate of maximum camber from leading edge 𝑥/𝑐 , maximum camber rate 𝑓/𝑐" are compared. As a result, maximum power output of turbine is reached around 1248W. Furthermore, additional improvement might be available by applying different set of the three design parameters between guide vane and hydro turbine.</p>
