“…From Table 2 and Figures 3 and 4, the results using the fine grid are similar to those of Hu et al (2020) in terms of hydrodynamic properties and the near-rudder flow field. Hence, the fine mesh is reliable for this study.…”

“…An E779A propeller and a rudder having the NACA0020 profile, whose geometric characteristics are listed in Table 1, are selected for this study. The configurations are the same as that used by Hu et al (2019bHu et al ( , 2020. The simulations are performed within a cubic computational domain of dimensions (l × w × h) 12.5D × 5.0D × 5.0D, where D is the diameter of the propeller.…”

“…All three meshes are constructed with the same boundary layer meshing and time step. Owing to a lack of experimental data, the comparison shown in Table 2 is conducted using data reported by Hu et al (2020). This table provides the discrepancy ( 21 and 32 ), convergence ratio (R G ), order of accuracy (P G ), error estimation (δ), correction factor (C G ), and uncertainty (U G ) among the results of adjacent meshes.…”

“…Figure 3 illustrates the distribution of the vertical vorticity of the rudder in each grid, and Figure 4 shows the vortex structures of the propeller, obtained using a Q-criterion of 1000/S 2 . The comparison is carried out between the results of present simulation and those by Hu et al (2020), in which the Q-criterion used is 1000/S 2 . The same value of Q-criterion is employed in present simulation.…”

The propeller wake can cause vibrations on the rudder surface, which worsen the noise and reliability. The vibration monitoring of the rudder operating in the propeller wake with fluid-structure interaction (FSI) method is still challenging. In the present study, the structural response during propeller-rudder interaction is investigated using detached eddy simulation. Three-dimensional distributions of loads, stresses, and deformations are discussed. The leading and trailing edges exhibit the strongest deformations in opposite directions, which are S-shaped. The strongest lateral deformation occurs between the tip vortex and hub vortex regions. In the tip vortex region, the dominant lateral vibrations fluctuate at the blade passing frequency (BPF) and shaft frequency (SF). However, the 75 Hz-fluctuation becomes significant at the trailing edge of the rudder. In the hub vortex region, the lateral deformation fluctuates mainly at 75 Hz except the area near the leading edge. There are weak vibrations occurring at the natural frequencies of the rudder when the natural frequencies of the rudder are much higher than the SF and BPF. However, the plate in the propeller suffers intense vibrations at the frequencies near the natural frequencies, where the natural frequencies of the plate are close to SF and BPF.

“…This aspect has been investigated by detached eddy simulation (DES) for a propeller in oblique flow at moderate loading and a rudder in neutral position (Hu et al. 2021). The study showed that the mean loads developed by the rudder (lateral force and torque) increased with the incidence of the flow as a consequence of the major kinetic energy of the slipstream associated with the stronger propeller loading.…”

The structural design of the rudder, traditionally based on quasisteady loads generated during worst manoeuvres, should account for load fluctuations associated with the interaction with the wake of the propeller in order to comply with the more stringent requirements on ship vibration and noise pollution. In this context, the present work analyses the dynamic response of a marine rudder located in the wake of the INSEAN E779A propeller by the one-way fluid–structure interaction approach. The time-dependent pressure distribution on the rudder, obtained through detached eddy simulation, is used to evaluate the pressure field that is the input for a structural solver to determine the resulting deformations and stresses. The computations consider the propeller at moderate loading, and rudder deflection angles at neutral and $4^{\circ }$ . The analysis discusses the different contribution of the tip and hub vortex of the propeller on the static and vibratory response of the rudder in the two configurations.
