Web innovation in horizontal wind pipe turbine propeler

Abstract

Abstract The efficiency limitations of wind turbines provided by Betz’s Theorem prompted researchers to develop new geometric shapes of wind turbines propeller that split pipe spiral slice by placing the web between turbine blades. The idea of developing the shape of the turbine was inspired by the shape of a duck’s or swan’s leg which has a web between its fingers that functions to obtain the thrust when swimming in water. The purpose of this study is to obtain the strength of material with optimal geometry and aerodynamic parameters in producing wind turbine efficiency. The method of obtaining research data is using solid work software for design, Ansys software for CFD simulations and Wind Tunnel laboratory equipment for experiments and also using Minitab 19 software for data processing. The results of the CFD simulation and experiment based research show that the turbine propeller turbine with using the web has higher efficiency than without the web.
