Operating a Three Blade-Wind Car with Wind Energy

Abstract

Airfoils have become a combined aspect of human flight as it has evolved over the last century. As the design of each airfoil determines many aspects of its use in the real world, all significant characteristics must be analyzed prior to implementation. The aerodynamic effects of pressure, drag, lift, and pitching moment are used to evaluate the behavior of the airfoil. The airfoil shape is expressed analytically as a function of some design parameters. The NACA 0012 and NACA 2412 are used with design parameters that control the camber and the thickness of the airfoil. Singularity method is the way to determine velocity distribution and pressure distribution of the airfoils. In order to apply it to the potential flow, Kutta condition and kinematic flow condition must be satisfied. It is expedient to treat a very thin profile. In this work, three vertical blades wind car, and directly connected to wheels by using of various kinds of links, and gears are used to convert the wind energy to mechanical energy to overcome the load that rotates the main shaft. The purpose of this work is to determine the torque, lift and drag forces of the different types of NACA airfoils that can be used in electric power generating or running our wind car. This was done by calculating of pressure distribution over the upper and lower surface of the airfoil to calculate the velocity distribution, lift and drag coefficient.
