A fully nonlinear non-dispersive energy balance for surfzone waves is derived based on the shallow water equations (NLSWE) to study nearshore dynamics of infragravity (IG) waves. Based simulations a relatively moderate and mild beach slope with non-hydrostatic wave-flow model (SWASH), new theory shows that spatial gradients in IG flux are nearly completely balanced by combined effect bottom str...

in this paper, a two-dimensional reynolds averaged navier-stokes (rans) model is developed to simulate the shoaling, breaking and overtopping of a solitary wave over a vertical breakwater. turbulence intensity is described by using a k turbulence closure model and the free surface configuration is tracked by volume of fluid (vof) technique. to validate the numerical model the simulation result...

We investigate the effects of wind–wave interactions on surface sea-spray-generation flux. To this end, Marine Aerosol Tunnel Experiment (MATE2019) was conducted at Pytheas Institute large wave–wind facility in Luminy (Marseille, France) over period June–July 2019. A unique range air–sea boundary conditions generated by configuring laboratory with four types wave forcing and five wind speeds sp...

This paper aims to apply two methods namely, Vortex Method and Higher Order Spectral Method to study the wave breaking and wave interaction. The breaking of shallow water gravity wave is performed using Vortex method, while the interaction between two gravity waves is carried out using Higher Order Spectral (HOS) method. In Vortex method an interface defined by a density or velocity discontinui...

The interaction between the hydrodynamics and complex bathymetry can produce highly heterogeneous and locally energetic flows, e.g., in a tidal inlet dominated by tidal flow and wave-current interaction. Consequently, the morphological evolution around such tidal inlet also becomes very dynamic. These two factors cause concerns over navigation safety especially in areas where routine surveys ar...

We present particulate simulation results for translational and rotational friction components of a shish-kebab model of a colloidal rod with aspect ratio (length over diameter) L/D=10 in the presence of a planar hard wall. Hydrodynamic interactions between rod and wall cause an overall enhancement of the friction tensor components. We find that the friction enhancements to reasonable approxima...
