The wake of a five-bladed marine propeller at design operating condition is studied using
large eddy simulation (LES). The mean loads and phase-averaged flow field show good …

A numerical analysis based on detached eddy simulations is conducted to investigate vortex
instabilities in the wake of a preswirl pumpjet propulsor. Three models are established to …

Results of large-eddy simulations of a submarine propeller in open-water (isolated)
configuration are presented for three load conditions. An immersed boundary approach is …

Large eddy simulations are presented on the wake flow of a notional propeller (the INSEAN
E1658), upstream of a NACA0020 hydrofoil of infinite spanwise extent, mimicking propeller …

It is important to predict the self-propulsion performance of full-scale marine vessels during
the design stage. With the development of high-performance computational techniques, full …

The wake dynamics and instabilities of a ducted propeller are numerically investigated at a
Reynolds number of R en= 1.765× 10 5. The numerical simulation is achieved by employing …

Recently, interest in underwater propeller noise has been increasing, especially submarine
propeller noise which is directly related to the survivability. The submarine propeller is …

The non-uniformity of the propeller wake field will lead to noise deterioration and structural
strength problems of the underwater vehicles. Therefore, the study of jet flow technology is of …

The present study reports results of Large Eddy Simulations (LES) in towed and self-
propelled conditions for the DARPA SUBOFF (DSub), a notional submarine geometry, at a …

A numerical study based on improved delayed detached eddy simulation is conducted to
investigate the flow of a pre-swirl pumpjet propulsor (PJP). The PJP consists of a stator, a …
