... obtained by Divya et al. , (2020). The mesh-based method is two dimensional and less time consuming, hence it is used in the region where wave generation is done. In the coupling zone, the wave parameters from 2D FNPT model are transferred to the particles of 3D IMLPG-R model which is further progressed...

... sea area. The influence of the wind and tide conditions were also analyzed. The results showed that the particles reached to the observation points faster during the ebb tide than the flood tide. The diffusion area of the oil spill was also larger during the flood tide. Under the condition of calm...

The mentioned particle-based FSI solvers have been validated through a set of benchmark tests. The key aspects...

... Abstract Horizontal plates are a common form of coastal engineering structures such as plate-form breakwaters, very large floating structures and wave energy converters. The scattering of solitary wave with a submerged horizontal plate is numerically investigated based on Smoothed Particle...

... drifter trajectories were compared with the numerical modelling results in Moreton Bay, Australia. Good correlation with an R2 of 0.73 between drifter data and modelled results was achieved indicating that the same set of model evaluations can be used to compute the particles spreading in further...

The traditional model with a constant friction angle is compared with the modified Mohr-Coulomb model with a shear-rate dependent friction angle, by comparing their predicted runout of dry...

... Abstract A two-dimensional wedge entering water is studied based on two-phase SPH (Smoothed Particle Hydrodynamics) method. We have designed wedges with different deadrise angle to study the cavity evolution and gas flow in the cavity. The liquid phase and gas phase are used by weak...
