時系列 PIV 計測による遠心ファン静翼近傍の変動解析

抄録

A centrifugal fan which will be equipped for HVAC on automotive was developed to aim high-efficient and environmental friendly device. In order to achieve the application for EV, especially, we have a fundamental demand of improvement of efficiency, performance, and noise reduction. In the present research for this sake, PIV measurement and CFD analysis are conducted for a fan of new concept in order to improve efficiency of HVAC system from the point of view of fluid dynamics. Then, verification of CFD analysis is reported by compering velocity fields visualized in terms of both methods.
