Unsteady Three-Dimensional Flow Behavior due to Rotor-Stator Interaction in an Axial-Flow Turbine

DOI Open Access

Description

<jats:p>Detailed unsteady flow surveys were conducted before, within and after the second-stage stator passage of a 1.5-stage axial flow turbine by using a single slanted hot-wire anemometry. Among the results reported in the present paper, of particular interest are the behavior of the rotor wakes and the rotor free-streams within the stator passage, and the spacially three-dimensional and time-dependent convection or mixing process between lower- and higher- energy fluids. Effects of the rotor-stator interaction causing unsteady secondary flows and tip-leakage flow are also discussed.</jats:p>
