ABSTRACT

This project presents the design, modelling and simulation of a wind turbine blade based on assumed local wind speed of 7m/s with a rotor performance of 10KW. These key values were plugged into QBl.Al)[ to design and model the blade using Blade Element Momentum (i3EM) Theory. A MATLAB prow-ani was developed to use (BEM) in designing a model of horizontal Axis Wind Turbine (I IAWI). NACAO() 12 airfoil was selected for the design of the wind turbine blade. The designed blade \\ asalso drawn and stress analysis conducted using SOIJI) WORKS. i)uring optimization it was obscr\'cd that the designed blade can operate optimally on increasing the wind speed li'om 7m/s to I 2ni/s. the optimal power generated was 53.528KW and the power value increases clue the increase iii air-velocity impact on the wind turbine blade. 'l'he designed blade had a coefficient of power of 0.3596 which falls within 13e1tz limit (0.25 0.40). The designed blade was seen to fail at I 000N/m2.
