Development and testing of novel small wind turbine (NSWT) set

Abstract

Wind energy is the important source being advanced to aid in the global climate change battle and to reduce dependence on non-renewable energy sources. This paper illustrates with a novel design of the blade shape to get more power production easily with low cost instead of using NACA (National Advisory Committee for Aeronautics) shape blade profiles. A prototype model of PVC (regular shape) and novel blades were tested under structural Finite Element analysis using ANSYS software package. Comparison between the two blades types with same specifications helps to give an idea to make the suitable prototype for development. The performance investigation of the blade prototype was carried out under actual conditions. The Investigation shows that the increment in the novel blade numbers caused turbine output power to grow in the range of 40 W–50 W for a wind speed of 0–10 m/s. The power collection increases up to 200 W utilized for domestic applications. The most competent structure recognized throughout the field testing is with five blades system. Nevertheless, it is prudent to declare that field test outcomes prove the existence of a new impression in wind blade design. Further, it is the first model of the novel mini wind turbine (NMWT), after successful lab testing it was subjected to full-scale field testing
