Boş Bir Boru Sisteminde Değişken Akımlı Bir Su Kütlesinin Paketinin Hidrodinamiği
Bozkuş, Zafer (1995-01-01)
Liquid slugs (water pockets) are propelled into an empty pipe under various driving pressures; the pipe's extension ends at an elbow whereon the slugs impact and disintegrate. Dynamic pressures recorded at various locations along the system indicate the complex and somewhat random structure of the transient. High-speed movies of the evolving slug just prior to impact show that significant air entrainment and breakup of the slug occurs. A simplified analytical model is developed to predict the slug dynamics;...
Hydrodynamics of Conical Spouted Beds With High Density Particles

An extensive experimental investigation of conical spouted beds with high density particles were carried out by measuring bed pressure drop, particle velocity and solids hold-up in a 15 cm ID conical spouted bed at three different cone angles (30°, 45°, 60°) with Yttria-stabilized zirconia (YSZ) particles (ρp = 6050 kg/m3 ). The results show that the minimum external spouting velocity increases with cone angle, particle diameter and static bed height. The bed is characterized by two regions: upward moving p...

Hydrodynamic picture of light trapping in integrated photonic nanostructures and metamaterials
Boriskina, Svetlana V.; Yerci, Selçuk; Chen, Gang (null; 2013-01-01)
We introduce a concept of light trapping on the nanoscale via pinning optical vortices to optimally-designed nanostructures, reveal this mechanism behind known focusing phenomena, and offer new approaches to design nanophotonic platforms and/or coupling schemes. © 2013 Optical Society of America.

The riser tube solar receiver of a circulating fluidized bed solid particle absorption solar thermal energy system was numerically modeled for analyzing hydrodynamic and heat transfer behaviors of the solid particles in the riser. Hydrodynamics of the model is validated by comparing radial distribution of void fractions with an experimental study. For the heat transfer from the opaque walls of the receiver that is heated to high temperatures by the solar rays concentrated by the heliostat field, a simple fr...
