The rotor blade modification in this research paper is a blade combination where the circle-shaped conventional model is combined with the one of a concave elliptical model. Two different blade geometries have been analyzed using a detailed computational Fluid Dynamics approach. The blade design will affect the simplicity of construction and cost of manufacture of turbine rotors. The aim is to analyze the influence of the blade combination towards the performance of hydrokinetic turbine for installation at a selected site. The research includes experimental method using open-type water tunnel of rotor's prototype with 2 different blade models of similar dimensions. The experiment shows, there are influences of the modification of the rotor blade to the performances of the turbine. The optimized blade design improves the performances of the Tip Speed Ratio (TSR) by 78 % while the Coefficient of thrust (CT) is improved by 58.3% at peak co-efficient of performance value of 0.47 for both the blade designs.
