Experiments were performed to understand the impact of orifice on droplet size in shear breakup region. Oil jet was released vertically from two types: a pipe and converging nozzle. The roll-up vortices observed clearly near edge with nozzle while elongated oil ligaments direction mostly orifice. droplets shed field layer increased along for both types. At different distances orifice, character...

The topic of the behaviour jets issuing from an orifice in lateral wall a pipe is interest many engineering fields, such as sea discharges pollutants via submerged pipes, diffusers to mix different fluids tanks and reactors, leakage industrial civil pipelines, etc. Most previous researches focuses on pressure loss across orifice, without taking into account modification internal flow and, most ...

BACKGROUND AND OBJECTIVES Natural orifice transluminal endoscopic surgery involves the introduction of instruments through a natural orifice into the peritoneal cavity to perform diagnostic and therapeutic surgical interventions. We report the utilization of the vaginal opening at the time of laparoscopic-assisted vaginal hysterectomy or total laparoscopic hysterectomy as a natural orifice for ...

Thermal properties of cryogenic fluids can profoundly change the nature cavitation since fluid pressure drop is not, anymore, only driving parameter this phenomenon. In research, we have conducted experiments inducing via a cylindrical orifice using Liquid Nitrogen as working and exploring regimes going from bubbly to full flashing. Among others, performed unsteady measurements derive speed sou...

URETEROCELE iS well known to genito-urinary surgeons, but it has attracted very little attention from pathologists or biologists. The usual description is that the primary condition is a pinhole ureteric orifice, with a dilated ureter above and a cystic projection into the bladder below, with the ureteric orifice on the surface of the cyst. Cystoscopically, the swelling expands and collapses ac...

We present the results of both experimental and numerical investigations silo discharge for a cohesive granular material. In our study, thanks to cohesion-controlled material (CCGM) we propose investigate effect length l c , on two different configurations, one axisymmetrical, quasi-2D rectangular silo. an adjustable bottom is used control size orifice. As observed cohesionless by previous stud...
