3D CFD Study of Scour in Combined Wave–Current Flows around Rectangular Piles with Varying Aspect Ratios

This study utilizes three-dimensional simulations to investigate scour in combined wave–current flows around rectangular piles with various aspect ratios. The simulation model solves the Reynolds-averaged Navier–Stokes (RANS) equations using the k–ω turbulence model, and couples the Exner equation to compute bed elevation changes. The model also...

A Combined Breakwaters System: A Wave Attenuation Study on the Combination of Submerged and Floating Breakwaters using REEF3D

Coastal zones have been a dynamic area and most favoured locations utilized for living, leisure, recreational activities, tourism, commerce and many other human activities. Submerged and floating breakwaters have been used as effective systems to protect these zones from wave attack. However, they are only effectively functional if the incident...

3D Numerical Modelling of Sediment Transport under Current and Waves

The sediment transport module of REEF3D is used to calculate the scour and the deposition pattern for abutment, pier and contraction under constant discharge and for pier under waves. The time development of scour for all these cases is also observed. To this effect, the Reynolds-Averaged Navier Stokes (RANS) equations are solved in all three...

Calculation of Wave Forces using REEF3D

Non-breaking wave forces on a cylindrical pile are calculated numerically by solving the three-dimensional Navier Stokes equations in the numerical wave tank of REEF3D. Initially, the numerical wave tank is validated by comparison of the numerical results with the analytical solutions for varying grid density, time step size, numerical beach...
