Bladeless Guide Vane for Centripetal Turbines

摘要

Investigations into the static conditions of a bladeless guide vane showed a sufficiently high effectiveness. This made it possible to confirm that the use of these guide vanes in centripetal turbines permit much simpler production technology and to reduce assembly weight and size without decreasing efficiency. The developed methods of approximate calculation make it possible with sufficient accuracy to design a bladeless vane for a given output flow angle. Nonuniformity of flow angles obtained in the experiments with respect to the periphery behind the guide vane may be explained by the presence of deviations of the flow areas of the fabricated chamber from those calculated.
