The wave-induced resonant flow in a narrow gap between stationary hull and vertical wall is studied experimentally numerically. Vortex shedding from the sharp bilge edge of gives rise to quadratically damped free surface response gap, where damping coefficient approximately independent wave steepness frequency. Particle image velocimetry direct numerical simulations were used characterise dynam...

A numerical investigation of hydrodynamics around a monopile foundation is presented in the paper. An open-source CFD program REEF3D used for present study. The model solves Reynolds-averaged Naiver-Stokes equation with k-w turbulence closure to obtain flow hydrodynamics. code utilizes staggered cartesian grid system. Also, Message Passing Interface (MPI) based parallelization domain decomposit...

ON SLOWLY VARYING STOKES WAVES by VINCENT HWA-HING CHU In this thesis investigations are made on the theory of a train of slowly modulated gravity waves propagating over uneven bottom topography. The primary object is to study the interplay of amplitude dispersion the frequency dispersion in waves on the surface of water where the depth is not too shallow compared to a typical wave length. The ...

While sea spray can significantly impact air–sea heat fluxes, the effect of produced by interaction wind and waves is not explicitly addressed in current operational numerical models. In present work, thermal effects were investigated for an idealized tropical cyclone (TC) through implementation different models into a coupled air–sea–wave system. Wave-Reynolds-dependent wave-steepness-dependen...

Migrating cells can extend their leading edge by forming myosin-driven blebs and F-actin-driven pseudopods. When coerced to migrate in resistive environments, Dictyostelium cells switch from using predominately pseudopods to blebs. Bleb formation has been shown to be chemotactic and can be influenced by the direction of the chemotactic gradient. In this study, we determine the blebbing response...

Gravity-capillary waves at the water surface are an obvious example illustrating wave propagation in laboratory, and also nonlinear phenomena such as interactions or turbulence. However, high-enough frequencies small scales (i.e., typically above 4 Hz wavelengths below 10 cm), viscous dissipation cannot be neglected, which complicates experimental, theoretical, numerical approaches. In this rev...

Green water events may present different features in the initial stage of interaction with deck a structure. It is therefore important to investigate evolution types green water, since not all interact at same time. In this paper, three (dam-break, plunging-dam-break, and hammer-fist) are studied. The surface elevations volumes over consecutive events, generated by incident [wave trains wave fl...

Furrow irrigation proceeds under several soil-water-furrow hydraulics interaction dynamics. The soil erosion consequences from such interactions in furrow irrigation in Samaru had remained uncertain. A furrow irrigation-induced erosion (FIIE) model was used to simulate the potential severity of soil erosion in irrigated furrows due to interactive effects of infiltration rates, land slope, and s...
