지면판위 복수장애물 주위 유동장의 가시화 (Ⅱ)

Abstract

地面板위에 모양이 서로 다른 복수 장애물을 바람방향과 평행으로 배열한 후(Tandem Arrangement)액체4염화 티타늄은 관찰대상 표면에 직접 도색하여 2차원 및 3차원 유동장을 효과적으로 可視化하였다. 유동장의 動的特性, 즉 박리영역의 양상, 방출 후류의 모양이 구조물의 배치모양과 구조물 사이의 간격에 크게 영향을 받고, 慝히 박리영역 내부의 역유가 확인 되었다.

Flow patterns around two-bluff cyliders in the tandem arrangements on a gound plane are effectively visualized using liquid titanium tetrachloride.

As results, it was observed that the form of seperated lines on the ground plane and the shedding of vortices from two cylinders were varied with both the gap width anda pair of different cylinders.
