Abstract

This study examines the flows near the different side mirrors by analyzing the flow due to air resistance at A, B and C models of automotive side mirrors. Model A is a square-shaped side-mirror. Model B is a triangular side-mirror and model C is an oval-shaped side-mirror. The air resistance of the side-mirror while driving is reduced and the automotive power can be reduced by changing the design of automotive side-mirror. As analysis result, as the pressure of air resistance against side mirror becomes larger, it can be seen that the air flow rate becomes great. Therefore, it can be estimated that the smaller the pressure of air resistance, the smaller the flow rate and the better the air flow. Therefore, it can be acknowledged that model B is the best model. As the design data of the automotive side mirror obtained on the basis of this study result are utilized, the esthetic sense can be shown while driving a car at real life.

본 연구에서는 A, B, C 3가지 자동차 사이드미러 모델들에 있어서의 공기 저항으로 인한 유동을 분석을 함으로서 다양한 사이드미러들 주위에서의 흐름을 연구한다. 모델 A는 사각형 모양의 사이드미러이고, 모델 B는 삼각형 모양의 사이드미러, 모델 C은 타원형 모양의 사이드미러이다. 자동차의 사이드미러의 설계를 변경함으로서 운전 시 좀 더 사이드미러의 공기저항을 줄여서 약간의 자동차의 동력을 감소시킬 수 있다. 해석 결과로서, 사이드미러에 대한 공기저항의 압력이 클수록 공기 유동속도가 큰 것을 볼 수 있었다. 그러므로 공기저항의 압력이 작을수록 유동속도가 작고 공기가 더 잘 유통된다고 판단된다. 그러므로 Model B가 가장 좋은 Model이라는 것을 확인할 수 있다. 본 연구결과를 토대로 얻은 자동차 사이드 미러의 설계데이터를 활용함으로서 실생활에서의 자동차 운전시에 그 미적 감각을 나타낼 수 있다.
