Numerical and structural investigation of flow past a helical axis wind turbine

Abstract

The present work is about designing a helical axis wind Turbine and testing its performance of both numerical and static structural analysis. NACA 0018 symmetric aerofoil is used as a turbine blade to modelling the vertical 3 bladed axis wind turbine rotor is tilted to an angle of 60 degrees, so as to get better performance of turbine. This paper deals, Numerical investigation of Helical Axis Wind Turbine (HAWT) with three blades has been carried out by means of both the numerical simulation and static structural analysis. The turbine performance can be observed by the span wise pressure distribution and velocity distribution, stress distribution and also observed that HAWT generated a power, which is an average power output incremental of 6.75 percent than precedes.
