DESIGN OF HORIZONTAL AXIS WIND TURBINE NACA4412 BLADE

Abstract

Wind energy is the rotary engine in which the kinetic energy of a moving fluid is converted in to
mechanical energy and generate electrical energy. Small horizontal axis wind turbines need to be
affordable, reliable and maintenance free for the average person to consider installing one. In this paper
the work was carried out to the aerodynamics design of a 500W horizontal axis wind turbine (HAWT) by
using blade element momentum theory (BEM) Wind energy is a very popular renewable energy resource.
In order to increase the use of wind energy, it is important to develop wind turbine rotor with high
rotations rates and power coefficient. In this work was carried out to the society for the domestic purpose
and the design of a 500W horizontal axis wind turbine by using Blade Element Momentum theory (BEM).
The generated design was scaled and built for testing purposes in the discharge of an axial flow fan of
1400 mm in diameter. This work will focus on review of Design and Simulation of Horizontal Axis Wind
Turbine rotor blades through General Public Licensed Software Q Blade. Q Blade utilizes the Blade
Element Momentum (BEM) method for the simulation of horizontal axis wind turbine performance. For
the design of custom air foils and the computation of air foil lift and drag coefficient poplar’s the viscousin viscid coupled panel method code XFOIL is integrated within the graphical user interface of Q Blade.
Blade is designed using Catia V5R20 Software using NACA 4412 air foil by calculated value by using tip
speed ratio of 4 , wind speed and angle of attack. This paper briefly elaborate the design of such a
horizontal axis wind turbine (HAWT) for domestic application and utility purpose.
