Abstract

The purpose of this study is to investigate the blade-to-blade flow in an axial compressor, providing a detailed description of the entire flow-field on multiple layers through the use of Particle Image Velocimetry (PIV). Typical problems that relate to flow seeding, light-sheet generation, and camera-laser timing control are successfully dealt with, bringing additional knowledge in the domain. An extensive data set is analyzed to obtain statistical flow information (mean and fluctuating quantities). Spatial data reconstruction procedures allow the complete planar flow distributions to be determined. The multiplanar mean velocity field constitutes the final result of a three-dimensional reconstruction of the domain geometry and the proper introduction of the available planar measurements.
