By using the particle image velocimetry (PIV) technique, experimental results of the propeller
jet flow field within a develo** scour hole around an open quay are presented. The …

The rotation of a ship's propeller can accelerate the water flow around it, which puts
pressure on seabed particles. Continuous pressure on the seabed can significantly trigger …

We present a new set of experiments in local scour due to confined twin propeller jets
aiming to include propeller driving characteristics to the analysis of the scouring action …

In recent years, seabed scouring caused by propeller jet flow impact, its resulting structural
and environmental effects, and the increase in the use of powerful engines with the …

Propeller-induced scour presents a significant challenge to the structural integrity of
seabeds near quay walls. This study explores the scour phenomena produced by co …

Single and twin ship propeller jets produce scour holes with deposition dune. The scour
hole has a maximum depth at a particular length downstream within the propeller jet …

The current research proposed the theoretical model for ship twin-propeller jet based on the
axial momentum theory and Gaussian normal distribution. The twin-propeller jet model is …

The growth of marine traffic in harbors, and the subsequent increase in vessel and
propulsion system sizes, produces three linked problems at the harbor basin area:(i) higher …

This research paper proposes the use of empirical equations to estimate the temporal
maximum scour that is induced by twin-propeller (ε twin= Ω t [ln (t)] Γ t) when acting over non …

The jet flow generated by manoeuvring ships nearby vertical structures is known to erode
the seabed sediment but is still difficult to predict the effects of a particular ship operating in a …
