Title: A study of unsteady flow induced by annular cascade

Abstract

The authors have experimentally studied phenomena of unsteady flow induced by annular cascade. The test apparatus consists of a swirl generator connected to a suction-type wind tunnel. The swirl generator duplicates variable inlet guide vanes (VIGV). The authors measured distributions of velocity flow by a hot wire anemometer and a three-hole Pilot tube, and pressure by semiconductor transducers. Results are: (1) the Strouhal number is independent of Reynolds number under each experimental condition; (2) the velocity wave propagates from pressure side of a vane to suction side of a neighboring vane; and (3) the setting angle of VIGV has effects on a fundamental frequency.
