Turbines are the most important part in a hydro power plant because here fluid energy is extracted from water and is converted into mechanical energy. Most of large hydro energy sources are already in use at present time so we need to concentrate on small sources to utilize their energy capacities. Axial turbines are best suited for low head power plants than other type of turbines in terms of performance. To extract the highest possible amount of energy from water, turbines should be designed to have maximum efficiency. There should be a better flow distribution inside the turbine space to have its increased efficiency. Flow behaviour inside turbine space largely depends on geometry of runner and distributor blades. In this paper a brief review of different design criteria and flow simulation techniques used for hydro turbines has been presented.
