Utilization of renewable energy in Indonesia is not at maximum capacity. Very-low head turbine is another method to utilize the low potential energy less than 2 m. This system have many advantages, for example; use renewable source energy, use low head, have simple civil construction and can be mounted at water gates Very-low head turbine has a few component that must be well design. <br /> <br /> <br /> The component consist of a runner, a guide vane, simple civil construction and other components that support the electricity generation system. The design of runner and guide vane is using the free vortex criterions and blade elements momentum approached as design axial turbine. The design of runner and guide vane assume have 90% efficiency and will be corrected at the simulation. The result of theoritical calculation at 800 rpm produce power of 2992 Watt, mass flow of 221 kg/s and head of 1.53 m. <br /> <br /> <br /> The reason of using Computational Fluid Dynamics (CFD) in runner and guide vane design is to simulate and corrected the design. The simulation used the Fluent 6.3.26 and give the result as follows: the parameter of simulation at 800 rpm and mass flow 280 kg/s, got 2120 watt of power, head <br /> <br /> <br /> 1.01m and 78.31% efficiency; the parameter of simulation at constant mass flow of 280 kg/s highest efficiency 79.24% at 1050 rpm; the parameter of simulation at constant rotation 800 rpm highest efficiency 78.31% at 270 kg/s.
