Air Dynamics A windmill can be approximated as a 'black box,' as shown in Figure 1 Wind comes in from the left, passes through the turbine, and exits at the right The way that a windmill gets power is by slowing down the passing air, so we imagine the simple case where there are two distinct air velocities to the left and right of the windmill
