Based on the enlightenment of contra-rotating propellers (CRP) and propeller boss cap fins
(PBCF), a numerical study of the contra-rotating propeller boss cap fins (CRPBCF) is carried …

The need of improving propulsive efficiency continuously encourages the development of
energy saving devices, the understanding of their underlying principles and the validation of …

In order to understand the effect of modifying the traditional form of propeller hub into the
propeller boss cap fins (PBCF) form, a series of tests was conducted to discover the best …

This study investigates the influence of roughness on hydrodynamic performance, especially
for the hub vortex—and, hence, hub vortex cavitation—of a benchmark propeller operating …

The propeller was one of the main propulsors in ships that consumed a lot of fuel due to the
viscous force acting in the ship. Therefore many studies have been carried out to increase …

This paper aims to cost-effectively improve the energy efficiency of large vessels in shipping
by the optimum design of propeller boss cap fins (PBCFs). First, a model propeller of the …

Numerical simulation is investigated to disclose how propeller boss cap fins (PBCF) operate
utilizing Reynolds-averaged Navier-Stokes (RANS) method. In addition, exploration of the …

Sažetak To investigate the vibration and noise reduction effects of Propeller Boss Cap Fins
(PBCF), the Large Eddy Simulation (LES) method has been employed in the noise …

In this paper, the efficiency of Propeller Boss Cap Fins (PBCF) installed at the bulk carrier
was estimated under both Propeller Open Water (POW) and self-propulsion conditions. For …
