Development of a hydrofoil wake oscillator model based on a near-vortex strength for predicting vortex-induced vibration on a hydrofoil International Journal of Naval Architecture and Ocean Engineering
Abstract Recently, the evaluation of vortex-induced vibration has emerged as a significantly important issue owing to the development of high-speed and lightweight ships and submarines. To derive an accurate vortex-induced vibration response, it is essential to consider the fluid-structure interaction. Moreover, it is necessary to evaluate the generation of the fluid-structure interaction to effectively prevent […]

Numerical Course-Keeping Tests of ONR Tumblehome in Waves with Different Rudder Control Strategies
Abstract This study aims to present numerical analysis on the course-keeping performance of an Office of Naval Research (ONR) tumblehome ship model in waves using an enhanced open-source library. The unsteady Reynolds-averaged Navier–Stokes (URANS) model coupled with a hierarchical rigid body motion solver is adopted to simulate free-running ships. An enhanced body-force propeller model for […]
Numerical investigations of flow over wavy cylinders at sub-critical Reynolds number
Abstract Numerical study of three-dimensional unsteady flow behind the double wavy (DW), singe wavy (SW), and smooth circular (SC) cylinders geometry at subcritical Reynolds number (Re=3.0×103) using large-eddy simulations based on the finite volume method are investigated in this study. This study contributes to the understanding of the effects of geometric disturbances as a passive […]
Mechanism of Axial Compresor Tip Clearance Noise Based on Taylor-Couete Flow Rotating Instabilty
Abstract Prediction of the tip clearance noise (TCN) of axial compressors is essential to accurately determine the noise level of the compressor, because it is left unattenuated during propagation. The existing studies on numerical methods are inadequate for accurate determination of the TCN owing to the limited understanding of the physical phenomenon. The most convincing […]
Fatigue damage prediction of ship rudders under vortex-induced vibration using orthonormal modal FSI analysis
Abstract Recently, the fatigue failure of ship rudders owing to vortex-induced vibration has increased as commercial ships become faster and larger. However, previous methods are inappropriate for fatigue failure prevention owing to the lack of fluid–structure interaction considerations. This study aims to develop a fatigue damage prediction method that can be applied at the design […]
