CFD를 이용한 연료전지 차량 수소 재순환 블로워의 성능 최적화

Regenerative blowers are widely used for hydrogen-recirculating system in fuel cell vehicle since they can generate high pressure in single stage. On the other hand, typical regenerative blower has its lower efficiency and is apt to lower total efficiency of the fuel cell car. Therefore improvement of both the performance and efficiency of blower at the same time is highly required. In this paper an effective CFD method of estimating the performance of blower was suggested and optimization of blower performance was performed. Optimized blower model was proved to have better performance and efficiency compared to base model.
