Abstract

Flow measurements on the propeller plane of a 180,000 TDW Bulk Carrier model are carried out using a 3D fiber optics LDV at a towing tank. Mean velocities are successfully obtained. The turbulence characteristics such as Reynolds stresses, skewnesses, and flatnesses, are also investigated. However, those turbulence characteristics may include some errors due to the characteristics of the towing-tank experiments.

3차원 Fiber Optics LDV를 사용하여 예인수조에서 180,000 톤급 살물 모형선의 프로펠러면에서의 유속을 측정하였다. 평균속도를 성공적으로 구하였으며 전단 응력, skewnesses 및 flatnesses 등의 난류특성에 대해서도 조사하였다. 그러나 이러한 난류유동 특성은 예인수조에서의 실험 특성상 약간의 오차를 포함하고 있다.
