SPH modelling of hydraulic jump at high Froude numbers at an abrupt drop: vorticity and turbulent pressure fluctuations
This paper numerically investigates the physical features of hydraulic jump oscillations at an abrupt drop with high Froude numbers reaching values up to 9.92. In order to emphasize the importance of the botto...

A multi-phase SPH simulation of oil spill diffusion in seawater currents
In case of oil spills due to disasters, one of the main environmental concerns is the oil trajectory and, consequently, its spatial distribution. In the present study, two-dimensional (2D) smoothed particle hy...

Open AccessEffects of global warming on Mediterranean coral forests
The effects of global warming have been addressed on coral reefs in tropical areas, while it is still unclear how coral forests are reacting, particularly at temperate latitudes. Here we show how mesophotic co...

Open AccessA mesophotic black coral forest in the Adriatic Sea
A forest of the black coral Antipathella subpinnata was found from 52 to 80 m depth in three different sites at Tremiti Islands Marine Protected Area (MPA; Mediterranean Sea), with two of them hosting a monospeci...

Characteristics of breaking vorticity in spilling and plunging waves investigated numerically by SPH
The present paper, places emphasis on the vorticity induced by wave breaking, which greatly contributes to sediments pick up and suspension as well as to air–water exchange at the wave interface, thus deservin...

Characteristics of nonbuoyant jets in a wave environment investigated numerically by SPH
Numerical experiments of plane jets are performed to investigate their behaviour into a still ambient and into a flow field of regular waves. SPH simulations are obtained by a pseudo-compressible XSPH scheme w...

SPH numerical investigation of characteristics of hydraulic jumps
In the present work, oscillating characteristics and cyclic mechanisms in hydraulic jumps are investigated and reproduced using a weakly-compressible XSPH scheme which includes both an algebraic mixing-length ...

SPH numerical investigation of the characteristics of an oscillating hydraulic jump at an abrupt drop
This paper shows the results of the smooth particle hydrodynamics (SPH) modelling of the hydraulic jump at an abrupt drop, where the transition from supercritical to subcritical flow is characterised by severa...

Synergistic use of an oil drift model and remote sensing observations for oil spill monitoring
In case of oil spills due to disasters, one of the environmental concerns is the oil trajectories and spatial distribution. To meet these new challenges, spill response plans need to be upgraded. An important ...

SPH numerical investigation of the velocity field and vorticity generation within a hydrofoil-induced spilling breaker
In the present work, the velocity field and the vorticity generation in the spilling generated by a NACA 0024 hydrofoil were studied. SPH simulations were obtained by a pseudo-compressible XSPH scheme with pre...
