The Prediction of the Optimum Performance of Venturi-Type Wind-Energy Concentrators
A simple theoretical analysis is presented which allows the optimum performance to be predicted for venturi-type wind-energy concentrators. The results of the analysis are presented in convenient parametric form in such a manner that, for example, the influence on optimum performance of reducing the outlet area of the exit diffuser, an obvious means of reducing the bulk and cost of a venturi-type concentrator, can be established directly from the curves. It is shown that the most important parameters affecting concentrator performance are: the effectiveness of the exit diffuser, the area ratio of that diffuser and the magnitude of the base-drag coefficient applicable at the diffuser exit plane. It was found that base-drag has the beneficial effect of lowering, below that of the surroundings, the static pressure prevailing at the outlet end of a concentrator
