Merlini, Stefano (2019) S-Duct Aerodynamics: Optical Distortion Correction Methods for the Application of Particle Image Velocimetry Techniques in Convoluted Aero Engine Intakes. [Magistrali biennali]
Full text disponibile come:
Complex flow phenomena and the high unsteadiness introduced by convoluted inlet ducts can compromise the performance of the downstream turbomachinery. Stereoscopic Particle Image Velocimetry has been successfully employed at Cranfield University to investigate the internal flow aerodynamics of unconventional intakes. In the present study, an optical distortion correction method based on calibration markers was developed along with an assessment of optical non linearities in PIV images.
