![]() The results of the CFD simulation was found that the phenomenon positioning of momentum force were place on the outer radius due to addition elbow tip cause increasing the torque. This research uses CFD simulation and experimental methods with a comprehensive study of the aerodynamic behaviour characteristics in and around the turbine rotor. The propeller using PVC pipe with elbow tip is the important part of new design which has been test with CFD simulation and wind tunnel research with best result performance. On the tip side installed the slice elbow with fit tip blade width. Face of blade on the hub side facing wind direction (axial) and face of blade on the tip side facing tangential direction or opposite with rotation. Dimension of width blade wider on the hub (3/4 of circular) and smaller on the tip (1/7 of circular). Material of blade propeller made by PVC pipe are slice half and twist from hub until tip with 90 degree of rotation. The purpose of this study was to determine the effect of variations in angle of attack and wind speed on the performance of a PVC pipe propeller wind turbine with an Elbow Tip. One simple technology is to use PVC pipe as the basic material for making wind turbine propellers. The potential of wind as an energy resource is still not widely used by the community through simple technology to produce electrical power.
