(Lisbon Symposia论文)使用PIV测量time trial helmets的

The paper focuses on stereoscopic PIV-3C measurements performed to investigate the vortical flow generated in the wake of helmets dedicated to Time Trial (TT) stages. The objective is to characterize the wake flow of TT helmet shapes and to provide the characteristics of the wake generated by different streamlined helmet geometries. The study specifically aims to provide detailed flow databases on helmet wakes in order to improve our understanding to identify efficient factors that may provide an efficient drag force reduction. 丹迪粒子图像测速仪 Dantec PIV
