Turbomachinery Fluid Dynamics and Heat Transfer

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.
