Trajectories of Water and Sand Jets
In this paper we introduce a correlation for the trajectories of sand jets, of a non-cohesive granular material, emerging from vertical sidewall orifices of diameter D and wall thickness w. A contrast with water ...

Experimental Study of a Vortex Generated at the Edge of a Channel with a Step
At the outlet of estuary-like systems, three vortices are formed: a dipole and a spanwise vortex. The spanwise vortex is formed due to the separation of the bottom boundary layer, just in front of the dipole. ...

Capillary Rise in a Taylor-Hauksbee Cell with a Tilted Edge
In this work we discuss a series of experiments to get the equilibrium profiles when a viscous liquid rises spontaneously in the wedge-shaped gap between two vertical plates intersecting at a tight angle ...

Isotherms of Natural and Forced Convection Around a Heated Horizontal Cylinder Embedded in a Porous Medium
This work presents an experimental analysis of free and forced convection due to a heated cylinder in a fluid-saturated porous medium. The resulting features of the temperature distribution under the action of...

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...

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...

Super Accelerated Flow in Diverging Conical Pipes
The motion of the upper free surface of a liquid column released from the rest in a vertical conical container is analyzed theoretically and experimentally. An inviscid one dimensional model for a weakly incre...

Traction Force Due to Aqueous Foam Flow Rising in a Vertical Pipe
This paper discusses in an experimental way the traction force exerted by a flow of aqueous foam through the annular space between a central rod and the inner walls of the pipe. These studies were made to prov...

Profile Deformation of a Non Cohesive Granular Material in an Accelerated Box
When a dry non cohesive granular material confined in a box in such a way that the initial profile of the free surface is a horizontal plane and it is accelerated uniformly, the final equilibrium profile chang...

Super Free Fall in Concentric Pipes
In the present work we have analyzed experimentally the characteristics of the free surface of a liquid column starting off of the rest in a vertical container (concentric tubes). We have two tubes of differen...

Capillary Rise in a Convergent Hele-Shaw Cell
The capillary rise of a viscous liquid into a convergent Hele-Shaw cell whose plates make a wedge-like channel along the downwards coordinate z has been analyzed theoretically by using the lubrication theory. ...
