Opis

Based on the proceedings of a symposium on Turbomachinery Fluid Dynamics and Heat Transfer, held at the Pennsylvania State University, University Park, this work offers research results as well as current insights into complex flow features found in the turbomachinery used for propulsion, power and industrial applications. It explains compressors, heat transfer fields in turbines, computational fluid dynamics and unsteady flows.

Spis treści

Complex flow fields in compressors and pumps: mixing mechanisms in multistage compressors; annulus wall boundary layer - flow into and through a rotating blade row; research and development of a transonic turbo compressor. Complex flow and thermal fields in turbines: near-wall full Reynolds stress closure in complex internal flow configurations - numerical implementations, 2D and 3D turbomachinery applications; secondary flow investigations in turbine cascades; film cooling in turbines - a review of the behaviour of discrete three-dimensional jets; thermal turbulence modelling techniques and applications; liquid crystal thermography on the rotating surfaces of turbomachinery systems; computational modelling of the generation and transport of aerodynamic losses in turbine blade rows; secondary flows in impeller passages; CFD research on axial-flow turbomachinery; a high convergence rate solution method, the residual cutting algorithm, in iterative solution of Poisson's equation; some unresolved physical problems in two-dimensional flows around blading; an interactive program for equilibrium-air thermodynamic and one-dimensional gas dynamic calculations. Unsteady flow: unsteady lase-doppler-velocimetry measurements in a cascade of controlled-diffusion compressor blades at stall; flow measurements in the moving blade passage of a single-stage axial-flow fan; rotating stall spatial domain characterization in axial and centrifugal compressors; recent fundamental research on turbine steady and unsteady aerodynamics at the National Aerospace Laboratory in Japan; unsteady acoustic wave propagation in a transonic compressor cascade.
