Abstract

In this study, the flow analyses were performed on the fluid clutch turbine blade shapes of models 1, 2 and 3, with eight turbine blades tilted at 45 °, 40 °, and 35 ° angles on the propulsion shaft, respectively. The larger the angle of inclination on the propulsion shaft, the higher the flow pressure among the flow models after the back of the turbine blades. On the other hand, the smaller the angle of inclination on the propulsion shaft of the turbine wing, the lower the flow rate. It can be seen that the smaller inclination angle of the turbine blade surface on the propulsion shaft, i.e., the wing shape close to perpendicular to the flow of fluid, is more suitable for efficiently connecting and disconnecting the fluid clutch. By applying the flow analysis by type of turbine blade of fluid clutch,the study result at this paper is considered to be favorable as the convergent research material which can apply the aesthetic design.

본 연구에서는 8개의 터빈 날개면들이 각각 추진축상에서 45°, 40°, 35°의 각도로 기울어져 있는 Model 1, 2 및 3인 3가지 Model의 유체클러치 터빈 날개 형상에 대한 유동 해석들을 수행하였다. 터빈 날개면이 추진축상에서 각도가 크게 기울어질수록 터빈 날개의 뒷면 이후에서의 흐름에서 Model들 중에서 가장 유동 압력을 크게 받고 있음을 알 수 있다. 반면에 터빈 날개면이 추진축상에서 각도가 작게 기울어질수록 유동 속도가 작게 된다. 터빈 날개면이 추진축상에서 각도가 작게 기울어질수록, 즉 유체의 흐름과 수직에 가까운 날개 형상이 효율적으로 유체클러치에 동력을 연결하고 차단하는데 있어서 적합함을 알 수 있다. 유체클러치 터빈 날개 유형별 유동해석을 적용함으로서 본 논문에서의 연구 결과는 미적인 설계를 적용할 수 있는 융합 연구자료로서 유리하다고 여겨진다.
