Numerical Simulation of a Spanwise Vortex in a Periodic Forced Flow
In geophysical flows, vortices are present at very different scales. Examples of them are the meddies, formed at the outlet of the Mediterranean Sea or the vorticity dipoles, occurring when water flushes from ...

Mass Flow Rate of Granular Material from an L-Valve Without Aeration
In this work we introduce a correlation to estimate the mass flow rate from an L-valve, without aeration, but under gravity flow, of a non-cohesive granular material. This criterion is based on the mass flow r...

Erosion and Deposition of Particles in a Periodic Forced Flow
In this paper we present an experimental study of the erosion and accumulation of particles produced by a periodic forced flow in two domains connected by a channel. For this purpose a thin layer of sand is de...

Flows from Bins: New Results
Gravity granular flows of cohesionless materials emerging from bottom exits and from lateral exit holes, both in vertical bins, and from face walls in tilted bins were modeled and measured. The models are base...

Singularities in Surface Waves
In this paper we investigate the evolution of surface waves produced by a parabolic wave maker. This system exhibits, among other, spatial focusing, wave breaking, the presence of caustics and points of full d...
