Due to recent crises of electricity in the country, it is utmost need for the utilization of renewable energy resources abundantly available like hydropower. To overcome this problem of electricity shortage, hydro-power turbines can be used. Since every hydro site have different site conditions, so design and selection of the proper turbine type and size becomes more important. In this case, it is vital to adopt indigenous design and development of hydropower components. Hydro turbines are the most important part of hydro-power plant. In this research, development of turbines has been focused, mainly of low head turbines. The reason is that small low-head schemes can easily be executed on the run-off-rivers and canals. This paper presents the optimization technique carried out on a complex geometry of blade profile through static and dynamic computational analysis. It is used through change of the blade profile geometry at five different angles in the 3D (Three Dimensional) CAD model. Blade complex geometry and design have been developed by using the coordinates point system on the blade in PRO-E /CREO software. Five different blade models are developed for analysis purpose. Based on the flow rate and heads, blade profiles are analysed using ANSYS software to check and compare the output results for optimization of the blades for improved results which show that by changing blade profile angle and its geometry, different blade sizes and geometry can be optimized using the computational techniques with changes in CAD models. After successful validation, five different blade profiles have been developed. Research results show improvement in the power output of the turbine with 5.43%. Future recommendations were also suggested to pave the way of further improvement in this area of specialization
