Abstract

In this study, a flow analysis is carried out on the wing shape of cooling fan at automobile. By designing three kinds of Canival, Teracan and basic models with CATIA program, this analysis is done on the configuration of cooling fan with the same flow condition. It can be seen that the contour of flow velocity is changed due to the model of wing and the pressure distribution of fluid is changed due to the configuration or the area of wing. In case of cooling model of Teracan among three models, there is the most air flow and it can be thought to be most effective to cool the radiator. And it is possible to be grafted onto the convergence technique at design and show the esthetic sense.

본 연구에서는 자동차 냉각팬에 대해서 유동해석을 수행하였다. 냉각팬의 형상에 대하여 유동 조건은 같게 하여 Canival, Teracan 및 basic 3가지의 모델을 CATIA프로그램으로 설계하여 본 해석을 실시하였다. 날개의 모양에 따라 유체의 속도의 등고선이 변화하는 것을 볼 수 있으며, 날개의 모양 또는 넓이에 따라 각기 다른 압력분포를 볼 수 있었다. 세 가지 모델 중, Teracan 모델인 냉각팬이 공기의 유동이 많아 라디에이터의 열을 식히는데 가장 효율적이 된다고 사료된다. 그리고 디자인 면에서의 융합 기술로의 접목도 가능하여 미적인 감각을 나타낼 수 있다.
