A STUDY OF THE FLUID DYNAMICS AND HEAT TRANSFER BEHAVIOR FOR RADIALLY INWARD FLOW OVER A SHROUDED ROTATING DISK

Abstract

The modeling of radial flow gas turbine fluid dynamics and heat transfer behavior is investigated. A test facility was constructed for the modeling of turbine flows. Several unconventional experimental techniques were developed for use in the facility. A simple model of a radial flow gas turbine was analyzed and tested. The fluid dynamics and heat transfer behavior of a single radially inward flow of air over a shrouded rotating disk was experimentally deter mined. The fluid dynamics behavior is presented as a series of graphs detailing the velocity profiles. The heat transfer is correlated over the operating range of radial flow gas turbines by a simple algebraic relation between the governing nondimensional parameters. An analysis is presented that does not adequately predict the heat transfer. The reasons for the discrepancy between analysis and experiment are discussed.
