Wind turbine blade is one of the key elements to convert wind energy to mechanical power. The aim of this paper is to enhance the passive and active techniques to control the flow and the loads on the turbine blades by developing and validating a simple finite element analysis (FEA) model of the turbine

IV. ANALYSIS WITH NOTCH Similarly the blade profile with notch is imported to ANSYS and various structural analyses is performed using three materials, aluminium–6061–alloy, GFRP and FML and the results are pictorially represented from Fig.14 – Fig.22. It is observed that the maximum stress and strain values are higher and the total deformation is lower due to introduction of notch, which increases the stability of the turbine blade.
