Establishment of Analytical Model for Peak Temperature Within a Sodium-Water Reaction Jet, (II) Mean Droplet Size in a Submerged Gas Jet

Modeling Gas-Solids Entrainment into a Horizontal Gas Jet Submerged within a Fluidized Bed

An entrained Droplet by an underexpanded gas jet into water

When a heat exchanger in a Fast Breeder Reactor cracks, highly pressurized water or steam escapes into the surrounding liquid sodium. A sodium-water reaction then occurs, forming disodium oxide (and hydrogen gas). It can cause secondary damages to the heat exchangers by the reaction heat and erosion corrosion. The released flow of steam from the cracks of the heat exchanger is an underexpanded ...

Hydrodynamic Behavior of Particles in a Jet Flow of a Gas Fluidized Bed

Numerous investigations have been devoted towards understanding the hydrodynamics of gas jets in fluidized beds. However, most of them address the problem from  macroscopic point of view, which does not reveal the true behavior in the jet region at the single particle level. The present work aims to understand the jet behavior from a more fundamental level, i.e. the individual particle leve...

Simulation Model for Weft Yarn Motion in a Single-Nozzle Air-Jet Loom

Air-jet weaving is an advanced weaving method with high efficiency and productivity. It is one of the most widely used methods of weaving in the world. In air-jet filling insertion, the motion of weft yarn is caused by friction between weft yarn and air blown through nozzle. After declamping and subjecting the yarn to air stream, its motion is not active but very complicated and influenced by ...

Mean Velocity and Static Pressure in a Sharp-edge Circular Nozzle Jet

An axisymmetric jet issued from a sharp edged circular convergent nozzle has been studied experimentally in the near field at Reynolds number 5.3x104  to search the saddle shape behavior of mean velocity and the role of mean static pressure in the jet flow. Due to the vena contracta effect the centerline mean velocity of the jet increases about 4.2% of its exit value and corresponding decrease ...
