The air flow through the gap 23 is thus enhanced first, due to the barrier effect of the central core 1 and secondly, due to the air flowing from the high pressure front side to the low pressure rear side The kinetic energy transferred from the air flow to the venturi rotor is a function of the mass of air flow in accordance with the equation...

In some cases, however, in a lower-wind-speed area, a smaller-diameter rotor can end up producing more energy than a larger rotor because with a smaller setup, it takes less wind power to spin the smaller generator, so the turbine can be running at full capacity almost all the time Tower height is a major factor in production capacity, as well ....
The effect of friction on winds in low pressure (cyclonic flow) and high pressure (anticyclonic flow) Figure 615A and 615B in The Atmosphere, 8th edition, Lutgens and Tarbuck, 8th edition, 2001 At low elevations, friction will slow the air, and hence the Co will be less effective in its deflection of the wind...
Windmills can not operate at efficiency because the structure itself impedes the flow of the wind The structure also exerts back pressure on the turbine blades as they act like an air foil (a wing on an airplane) In most all cases, the efficiency of the wind turbine depends on the actual wind speed...
