Effects of axial and radial-gap spacing on the local heat transfer of a shrouded rotor-stator system
- Carnegie Mellon Univ., Pittsburgh, PA (United States)
Unlike the free disk in which heat transfer is primarily affected by rotational speed, heat transfer in rotor-stator systems is influenced by the operating conditions as well as system geometry. In a rotor-stator system with no radial shroud, commonly referred to as an open rotor-stator, Kreith et al. (1959, 1963) and Metzger (1970) demonstrated that the presence of the stator influences heat transfer from the disk at axial gap spacings less than 10 percent of the disk diameter. These studies also examined the effects that forced coolant flow introduced at the hub of the system has on the average heat transfer rate. As an extension of these studies, more recent evaluations by Metzger et al. (1979, 1991) and Popiel and Boguslawski (1986) have examined the effects of varying the location and rate of forced coolant flow. 10 refs., 4 figs.
