This work mainly analyzes the variation laws of exciting force, pulsating pressure, velocity
distribution and hydrodynamic parameters of PJP at different tip clearances (δ= 0.5 mm, δ= 1 …

The hydrodynamic excitation generated by a propeller rotating in nonuniform inflow causes
the propulsion shafting to vibrate, and this vibration feeds back to the propeller …

Pump-jet propulsors, which exhibit high efficiency and low noise, are widely used in
underwater vehicles. In a marine environment, a nonuniform wake and an oblique flow affect …

In this paper, the unsteady exciting characteristics of a marine propeller influenced by the
shafting whirling vibration effect are numerically studied by employing the dynamic sliding …

In this study, the SST k− ω turbulence model and the sliding mesh technology based on
RANS method have been adopted to simulate the exciting force and hydrodynamic of a …

In this study, a detailed analysis of hydrodynamic performance of a pumpjet propulsor (PJP)
in different oblique inflow angles (β= 0⁰, 5⁰, 10⁰, 15⁰, 20⁰, 25⁰, 30⁰, 40⁰) and different …

The occurrence of a tip leakage vortex (TLV) is a special phenomenon of ducted propellers,
which has a significant influence on the propeller's hydrodynamic performance and …

The hydrodynamic loads and wake dynamics of the ducted propeller in oblique flow are
investigated by detached eddy simulation (DES), with particular emphasis on the …

For a propeller vibrating in a fluid, the added mass and damping coefficients characterize
the hydrodynamic forces and moments acting on the propeller, which are of great …

The vector propulsion systems have been equipped in numerous autonomous underwater
vehicles (AUVs) nowadays. In most cases, the vector propulsion is achieved by changing …
