Wind Analysis, Blade Design And Modelling For Ikeja, Nigeria

ABSTRACT

This research presents a technical assessment of wind power potential of Ikeja city, Lagos

state, Nigeria to determine its viability for wind turbine system. Initially Weibull probability

distribution 's two-parameter model was used for the mathematical modelling and design

using data harvested at 2m height. When extrapolated at higher regions of altitudes of

30meters, wind speed was found to be between 22.66 to 29.9 ni/s while the monthly power

densities were in the range of 6996 <WPD< 16097 W/m2, Similarly, maximum monthly mean

wind energy density (WED) values at the same height yielded 11976 Kwh/m2which is

effectively good for wind turbine applications. These key local parametric values were

plugged into Q-BLADE to design and model a tailor-made blade using blade-element

momentum theory (BEM). The designed blade was also drawn and stress analysis conducted

using SOLID WORKS, the blade was seen to fail at J000N. The coefficient ofpoiver of the

designed blade was 0.335 which falls within beltz limit (0.59).
