An Investigation into the impact of the spanwise flow field at rotor inlet on the performance of mixed flow turbines
… approaches were considered. The first was leaned stator vanes, which were investigated using numerical and experimental techniques. The second approach was multi-scroll volutes, which had asymmetric limbs on the hub and shroud sides of the passage. These were examined with a numerical analysis. …

Random-vortex-particle methods applied to broadband fan interaction noise
… interaction between upstream turbulence and the stator vanes. The stochastic method developed to generate synthetic turbulence reproduces twodimensional isotropic turbulent flows by filtering a random field. The fillter is expressed in terms of the energy spectrum and controls the spatial …

Manufacturing and analysis of a LIGA heat exchanger for the surface of a tube: a cooling simulation of the leading edge region of a turbine blade
… cooling is required includes gas turbine blades, stator vanes, the turbine disk, and the combustor liner. In this dissertation, the primary application of interest is the use of such heat exchangers to cool airfoils such as turbine blades. In the first part of the study, the manufacturing and …

Scattering of an entropy disturbance into sound by a linear cascade of turbine stator blades
… between the entropy disturbance and turbine stator vane. Combustor-produced entropy disturbances have been simulated both in the form of a plane wave and localized high frequency pulse. DNS results for the interaction of an entropy disturbance with turbine stator vanes are presented and the …

A Comprehensive Three-Dimensional Analysis of the Wake Dynamics in Complex Turning Vanes
… structures formed in the wake of complex turning vanes. The vane packs were designed by the StreamVane swirl distortion generator technology, a design system that can efficiently reproduce swirl distortion for compressor rig and full turbofan engine testing. StreamVanes consist of an array of …

Unsteady Turbulence Interaction in a Tip Leakage Flow Downstream of a Simulated Axial Compressor Rotor
… operating in the vortical wakes of a set of stator vanes. The cascade, consisting of 8 GE rotor B blades, has adjustable tip gap, inlet angle of 65.1 degrees, turning angle of 11.8 degrees and solidity of 1.076. The cascade Reynolds number, based on blade chord, was 393,000. A moving end wall …
