Investigation on hull-propeller-rudder interaction by RANS simulation of captive model tests for a twin-screw ship

Contribution of tip and hub vortex to the structural response of a marine rudder in the propeller slipstream

“…2017 b ; Guo et al. 2018). Since the focus was on spatial and temporal scales of the hull, this issue has been typically tackled by a quasisteady modelling – the actuator disk theory – of the propeller–rudder interaction, thus neglecting the details of the vortical structures dynamics.…”

“…This approach has been traditionally boosted by the necessity to develop comprehensive mathematical models that could assess the control and manoeuvring qualities of the ship in earlier design phases. In these models, the critical item has been always the representation of the interaction between the hull, propeller and rudder, assessed by time consuming experimental or, more recently with the increasing feasibility of viscous based solvers, numerical tests (Molland & Turnock 2007;Liu & Hekkenberg 2017;Muscari et al 2017b;Guo et al 2018). Since the focus was on spatial and temporal scales of the hull, this issue has been typically tackled by a quasisteady modelling -the actuator disk theory -of the propeller-rudder interaction, thus neglecting the details of the vortical structures dynamics.…”

Powering Performance Prediction of a Semi-Displacement Ship Retrofitted with Hull Vane

“…Specifically, the difference in the propeller rotational speed between the CFD results obtained using the discretized propeller model and the experimental data is less than 2%. To enhance computational efficiency, some applications (Guo et al, 2018;Guo and Zou, 2021) incorporate a coupled version of MRF and sliding mesh techniques. This approach is particularly useful since the sliding mesh technique requires more computational time due to the complex interaction between the rotating and stationary regions.…”

Numerical Analysis of the Rudder–Propeller Interaction

“…In the past, several researchers worked on this topic using both experimental (among the others [13][14][15][16]) and numerical approaches. Different numerical approaches have been adopted in the reference literature, ranging from simpler potential ones (see for instance [17][18][19][20][21]) up to more demanding ones based on the complete flow equations ( [7,[22][23][24]). Particular attention should be paid also to hybrid methods, which try to merge the benefits of both approaches, consequently reducing the overall computational costs (among the others [5,25,26]).…”

“…The researchers who adopted numerical codes have focused their attention on different flow problems, ranging from the isolated rudder condition, often with peculiar rudder shapes ( [14,15]) or when it interacts with a propeller ( [27,28]). Others, on the contrary, considered the more complex problem which includes the mutual interactions of the complete system, i.e., rudder-propeller-hull (as in [24]).…”
