Abstract

Recently sloshing that fluid in fuel tank is undulating by the external force during motion of automobile, ship and aircraft is greatly affecting by damaging the inside of structure. It's most important to precisely analyze the behavior of fluid by computational fluid dynamics for minimizing the effect of sloshing for the loaded fuel. This study characterized volume of fluid and pressure according to the length and number of vertical baffle and horizontal baffle in fuel tank for Kia Frontier cargo and analyzed for reduction of sloshing during driving on corner and hill by using ADINA-CFD. As a result of analysis, the optimum length for sloshing reduction shows 0.19 m for vertical baffle and 0.08 m for horizontal baffle. And it shows that vertical baffle is better for the reduction effect of sloshing during driving on corners, on the other hand, horizontal baffle is effective and stable during driving on hills.

최근 자동차, 선박, 항공기의 운행시 외력에 의해 연료탱크 내의 유체가 출렁거리는 슬로싱 현상으로 인하여 구조물 내부가 손상되어 큰 영향을 미치고 있다. 따라서 적재연료의 슬로싱 영향을 최소화하기 위해서 전산유체역학적으로 유체의 거동을 정확히 해석하는데 무엇보다 중요하다. 본 연구에서는 ADINA-CFD를 이용하여 Kia 프론티어 Cargo용 연료탱크에 수직배플과 수평배플의 길이 및 개수에 따른 유체유량 및 압력의 특성을 파악하고, 코너 및 언덕 주행시 슬로싱 감소를 위해 해석하였다. 그 결과로 슬로싱 감소효과를 위해 배플의 최적길이는 수직배플의 경우 0.19 m, 수평배플의 경우 0.08 m로 나타났다. 그리고 자동차주행 경우에 코너주행 시는 수직배플이 수평배플보다 슬로싱 감소효과를 보이는 반면에, 언덕주행 시는 수평배플이 효과적이며 안정성을 나타내었다.
