Particle trajectories in linearized irrotational shallow water flows
, 2008 We investigate the particle trajectories in an irrotational shallow water flow over a flat bed as periodic waves propagate on the water's free surface. Within the linear water wave theory, we show that there are no closed orbits for the water particles ...

A fresh look on old analytical solutions for water waves on a constant slope; pp. 422–429 [PDF]
Proceedings of the Estonian Academy of Sciences, 2015 The first studies of water waves climbing a beach of constant slope were restricted to standing wave solutions. They all used potential flow theory. Various methods can be found in the literature. Hanson (The theory of ship waves. Proc. Roy. Soc. Lond. A

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion
Advanced Engineering Materials, EarlyView.This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

The “shallow-waterness” of the wave climate in European coastal regions [PDF]
Ocean Science, 2017 In contrast to deep water waves, shallow water waves are influenced by bottom topography, which has consequences for the propagation of wave energy as well as for the energy and momentum exchange between the waves and the mean flow.

Geometric phases of water waves
, 2014 Recently, Banner et al. (2014) highlighted a new fundamental property of open ocean wave groups, the so-called crest slowdown. For linear narrowband waves, this is related to the geometric and dynamical phase velocities $U_d$ and $U_g$ associated with ...

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Waves in a fluid layer excited by pressure variations above the free surface [PDF]
Геосистемы переходных зонThe aim of the paper was to study the problem of waves in a layer of incompressible fluid of constant depth. The interest in the problem arose due to the excitation and propagation of surface waves in the Pacific Ocean as a result of the powerful ...
