Turbulence flows are often founded in the flow of fluid engineering works such as the air flow through a wind turbine blade and water flow through a wheel of water turbine. Computational fluid dynamics (CFD) is now recognized as an essential design tool for engineering. The research presents the proposed results of analyzing the performance of horizontal axis micro water turbine generator for community, using computational fluid dynamics (CFD) technique by application using K-epsilon ( ) and K-omega SST ( ) Turbulence model for calculation and rotational analysis from the solidworks flow simulation program version 2014. The modeling is 150 mm. diameter using for the efficiency prediction in numerical method. The water turbine simulation producing the electricity is numerical modeled by varying flows through the wheel of vertical axis micro water turbine. The duplication of the numerical is modeled by the control volume methodology. Additionally, it is easier for solving of the conservations equations using mass and momentum theory. It is found that average head is 2.23 m, water velocity is 6.61 m/s, wheel speed is 214 rpm and torque generate is 9.01 N.m. The micro water turbine type is designed to be horizontal axis micro water turbine. The result reveals that the designed RPM is suitable for this flow condition.
