Laser-optical investigation of stator-rotor interaction in a transonic turbine

(2006) Laser-optical investigation of stator-rotor interaction in a transonic turbine, 1 ABSTRACT This paper presents research in a highly-loaded cold-flow transonic turbine under continuous and engine like conditions. Special focus was placed on blade row interaction at app. 10600 rpm. While the first step was the investigation of a single stage machine (stator-rotor), the second step extended...

Rotor Wake Characteristics of a Transonic Axial Flow Fan HC A 02 / K A 01 Unclas G 3 / 02 « 3371

State of the art turbomachinery flow analysis codes are not capable of predicting the viscous flow features within turbomachinery blade wakes. Until efficient 3D viscous flow analysis codes become a reality there is therefore a need for models which can describe the generation and transport of blade wakes and the mixing process within the wake. To address the need for experimental data to suppo...

Aerostructural Optimization of a Transonic Compressor Rotor

This paper presents a framework for multi-objective and multidisciplinary design optimization using highfidelity analysis tools. In this framework the aerodynamic performance is evaluated based on a Navier–Stokes equation solver, and the structure dynamics is computed using commercially available finite element software. We employ a genetic algorithm as a robust design optimization tool to faci...

Rotor Wake Investigation Using the Smoke Flow Visualisation Technique

Experiments were carried out on a small four bladed rotor at different climb rates. The smoke-filament technique was used to visualise the rotor tip vortices; video equipment was then used to record the images produced. The recorded images were digitised and enhanced to assist in the identification of the vortex location. The vortex trajectories were compared with established data and with the ...
