Nowadays great interest of renewable energy production systems since last few years. The renewable energy sources such as a hydro, solar and wind have been rapidly growing, especially the hydropower energy due to the increasing of predicted scarcity of fossil fuels and the environmental issues. Kaplan turbine is a reaction type of hydropower which is one of the primary sources of renewable energy. In this study, the aim of this work is to design and performance investigation of a Kaplan turbine runner for determining the power output and efficiency based on different configurations of turbine wheel. The main characteristics of a micro Kaplan turbine primary proposed design configurations was performed to increase the use of renewable power in rural areas and reduce the dependence on fossil fuels. The computational fluids dynamics (CFD) was used to simulate the proposed design for further analysed and improve both the power output and efficiency using ANSYS CFX17.1.The performance of a micro Kaplan turbine has been predicted such as power output and efficiency. Furthermore, the effect of blades number showed a significant influence on the turbine’s power output and efficiency. Generally, improvement of proposed design configurations are presented for understanding the flow field in a Kaplan turbine runner.
