Abstract
To analyze the complex three dimensional flow structure of an Turbo-fan and determine the validity of its application, PIV is used to provide detailed space and time resolved experimental data for understanding and control of flow field. The high resolution PIV, was successfully employed in this study for the investigation of flow structure in and around the Turbo-fan. The three-dimensional velocity fields, turbulent intencity and mean vorticity distributions of the stereoscopic PIV measurement results were represented at rotor exit region.. From the velocity distribution, the vorticity and turbulent intensity distribution, which are known to be major factors of fan noise, were calculated.
