Journal ArticleDOI
On the wake dynamics of a propeller operating in drift
TL;DR: In this article, the onset and the nature of dynamic instabilities experienced by the wake of a marine propeller set in oblique flow are investigated by means of detached eddy simulations, in particular, the destabilization process is inspected by a systematic comparison of the wake morphology of a propeller operating in pure axisymmetric flow and in drift with angle of 20°.
Journal ArticleDOI
Simulation of turning circle by CFD: Analysis of different propeller models and their effect on manoeuvring prediction
TL;DR: In this article, the turning circle manoeuvre of a self-propelled fully appended twin screw tanker-like ship model with a single rudder is simulated by the unsteady RANS solver χnavis developed at CNR-INSEAN; several propeller models able to include the effect of the strong oblique flow component encountered during a manoeuvre have been considered and compared.
Journal ArticleDOI
Analysis of the performances of a marine propeller operating in oblique flow
TL;DR: In this paper, a marine propeller working in oblique flow conditions is numerically simulated by the unsteady Reynolds averaged Navier-Stokes equations (uRaNSe) and a dynamically overlapping grid approach.
Journal ArticleDOI
Turning ability analysis of a fully appended twin screw vessel by CFD. Part II: Single vs. twin rudder configuration
TL;DR: In this paper, the analysis of the turning capability of the naval supply vessel presented in Part I (Broglia et al., 2015) is continued with different stern appendages, namely twin rudder and centerline skeg.
Journal ArticleDOI
Analysis of propeller bearing loads by CFD. Part I: Straight ahead and steady turning maneuvers
TL;DR: In this paper, the correlation between inflow conditions and propeller loads is investigated by means of URANS simulations and simplified propeller theories for the same twin screw model recently considered in free running maneuvering model tests (Ortolani et al., 2015a, 2015b).
