Horn-type Rudder 주위의 2 차원 난류유동 해석

다국어 초록 (Multilingual Abstract)

The two-dimensional turbulent flow around the horn-type rudder has been examined in the present study by using the commercial code FLUENT. The standard k-ε model is used as a closure relationship. The geometry of horn rudder is based on the NACA 0020 airfoil. The simulations for various angle attack (α) and yaw angle(δ) are carried out. The effect of Reynolds number is also investigated in this study. The cavitation is more possible when the yaw angle is 6° and it is more serious as Reynolds number increases.
