Abstract

This study discusses about the design and analysis mini hydro power turbine blade. The mini hydro power turbine has become more useful since the dam construction is too high cost and ecosystem impact. As the flow rate of the rivers or stream is lower comparing to the dam construction, the mini hydro power turbine is needed to be to generate electricity in the low water velocity and low head. Hence, the spiral turbine blade is decided to be analyzed and fabricated by 3D printer in this experiment. This kind of turbine blade can be operated in low water velocity and low head thus it can avoid harming the marine life. The spiral turbine blade’s surface area and its own blades are suitable for low velocity as its small radius can generate a little traction force. The spiral turbine blade is designed by Quality Functional Deployment (QFD), Morphological chart and Failure modes, effects, and critical analysis. It is then drawn by using SOLIDWORKS software. Furthermore, the spiral turbine blade is fabricated by using 3D printer, so the processing time has been reduced and cost saving. The material that used by produce spiral blade is Polyamide 12 as this kind of material can withstand high pressure and high-water velocity. Moreover, the flow simulation and pressure simulation are analyzed by Computational Fluid Dynamics (CFD). The results of voltage produced, and rotational speed of spiral blade will be recorded in both experiments which are spiral turbine blade with and without the chamber. The results of efficiency of spiral blade is calculated and will be compared in between spiral blade with and add without the chamber. The results showed that the spiral turbine blade with installing collecting chamber can produce higher velocity, rotational speed, and voltage than without installing collecting chamber
