국문 초록

This study investigates the influence of key kinematic parameters—particularly oscillation frequency (ω₁′)—on hydrodynamic coefficients through CFD-based pure sway and pure yaw simulations of the HANNARA training ship. The results show that higher oscillation frequencies yield significantly larger sway forces and yaw moments, leading to increased values of coefficients such as Y′_v, Y′_vvv, N′_v, and N′_vvv. However, added moment of inertia (J′_z) showed inconsistencies at higher frequencies. While coefficients derived from pure yaw tests exhibited noticeable errors in predicting manoeuvring performance, combining them with rotating arm simulation results from previous studies significantly improved the accuracy of turning and zigzag manoeuvre predictions. These findings highlight the importance of selecting appropriate hydrodynamic coefficients to enhance the reliability of ship manoeuvring models.
