N2 - Instead of connecting the penstock pipe to the nozzle, the connector is also designed to increase the speed of water entry. Therefore, an angle between the connector and the nozzle is needed which is called the connector angle. However, when the connector angle is too large, it can cause the direction of flow at the blade entry is changed. Therefore, this study is intended to compare the performance of the turbine with 3 variations of the connector angle which are 1000, 1050, and 1100. This study is conducted with 2 dimensional computational fluid dynamics analyses. Ansys Fluent 18.1 was used with multiphase volume of fluid (VoF) models. The results of this study reveal that the connector angle affects the performance of the cross-flow turbine. This study shows that a connector with 105° angle generates the higher efficiency compared to connector angle 100° and 110° with highest efficiency value is 83.4%. Additionally, the maximum efficiency of the all cases was obtained at a blade rotating speed of 800 rpm.
