Pengaruh jumlah sudu terhadap unjuk kerja 3D print turbin air tipe vortex

The potential of natural resources in the form water energy is a renewable resource that often used because it does not damage environment and can be continuously. This flow has two types, namely laminar turbulent flow, forces generated from these flows are also different. Turbulent tends to produce greater force lift object masses better than flow. Therefore, vortex turbine emerged which utilizes as waterwheel drive, by directing towards cross section converting into utilizing gravity cross-sectional shape forms whirlpool move turn turbine. number blades very influential on performance affects resulting output, voltage, current, rotational speed, torque efficiency. In this study, best results were shown with total 6, at speed 141.3 rpm; voltage shows result 0.28 volts; current produces 44 mA; Torque (Nm) 0.22 Nm; efficiency 76.5%.
