Knowledge of the dynamics of propeller wakes is fundamental to design and optimize the
next-generation propellers. This work aims at investigating the wake instability of a propeller …

This study investigates the influence of blade number on the propulsion performance and
excitation force of pump-jet propellers (PJPs) using computational fluid dynamics. The …

A pump-jet, which is generally and widely adopted on underwater vehicles for applications
from deep sea exploration to mine clearing, consists of a rotor, stator, and duct, with the …

A numerical study based on detached eddy simulations is conducted to investigate the
effects of the odd and even number of rotor/stator blades, that is, nr/ns, on the hydrodynamic …

The purpose of this study is to investigate the effects of cavitation on the hydrodynamic
loading and wake vortex evolution in a pre-swirl pump-jet propulsor, and also the cavitation …

Noise emitted from a rotor due to its interaction with ingested turbulence is dominant for
modern submarine propulsors. An experimental study of broadband thrust from a couple of …

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 …

In this study, a new method for controlling the tip leakage vortex of a pumpjet propulsor is
developed by adding rectangular axial slots to the inner wall of the duct. The first objective of …

In this numerical study, a modal approach based on the stress blend eddy simulation
(SBES) was employed to investigated the morphology and development regime of the …

In the current paper, high-fidelity improved delayed detached-eddy simulations (IDDES)
using the OpenFOAM library are employed to characterize the performances and the wake …
