Study of Three-Dimensional Internal Flow Distribution based on Measurement in a 48-inch Radial-Inlet Centrifugal Impeller

sehr guter Zustand, geringe Gebrauchs- und Alterungsspuren: Deckel und erste Textseite mit altem Stempel, Deckel auch noch mit Nummer und Notiz - Seiten sauber und ordentlich A study of the loss and velocity distribution in a radial flow impeller was made. It is indicated that secondary flows within the boundary layer and leakage through the blade-to-shroud clearance space result in a concentration of low-energy air at approximately 80 percent of the passage width from the pressure face at the shroud. Comparison of the data from internal measurements made for the impeller of this investigation with hot-wire anemometer studies made at the outlet of a similar impeller indicates that much can be learned about the internal flow picture with hot-wire surveys alone.
