Energy transfer between the interacting waves in a distributed Brillouin sensor can result in a distorted measurement of the local Brillouin gain spectrum, leading to systematic errors. It is demonstrated that this depletion effect can be precisely modelle ...
Surf and swash zone hydrodynamics are complex, being composed of a highly energetic water-air mixture under periodically unsteady motion. Wave-current interactions have a major effect on the results of hydrodynamic simulations, and consequently on predicti ...
elements. In addition to a prismatic reference channel, 41 different configurations of rectangular bank cavities have been investigated. The purpose was to study the effect of large-scale bank roughness on steady and unsteady flows. The macro-roughness of ...
The main objective of this study was to develop further understanding of surf-swash zone hydrodynamics under a variety of wave forcing conditions. The main tool used was a comprehensive two-phase numerical model – combining two-dimensional wave solver with ...
This paper presents a Lagrangian approach for the simulation of two-dimensional free-surface flows along with a systematic validation. Fluid-flow is traditionally modeled using an Eulerian description in association with finite differences and, more recent ...
Energy transfer between the interacting waves in a distributed Brillouin sensor can result in a distorted measurement of the local Brillouin gain spectrum, leading to systematic error. We demonstrate here that this behavior can be fully and precisely model ...
We present a theoretical stability analysis of the flow after the sudden release of a fixed mass of fluid on an inclined plane formally restricted to relatively long time scales, for which the kinematic regime is valid. Shallow-water equations for steep sl ...
Systematic investigations on positive and negative surge waves from upstream have been conducted in a 40 m long channel with a mean bed slope of 1.14? and non-prismatic bank geometries. The channel banks included macro-roughness elements, namely various ca ...
The two-dimensional two-phase Navier-Stokes equations, volume of fluid technique and a two-equation turbulence closure model were used to predict wave breaking and runup, and compared with experimental data. Comparison of the results with a corresponding s ...
In this study, adiabatic vertical cocurrent downward air-water flow in an 8.8 mm internal diameter channel was investigated using non intrusive optical techniques. Flow pattern tests were performed to assess the influence of the inlet device, of the test s ...
