Disintegration Model of Liquid Jet Injected from Coaxial Airblast Atomizer.

Spray Characteristics of a Liquid-Liquid Coaxial Swirl Atomizer at Different Mass Flux Ratios

An experimental investigation is performed to explore the characteristics of sprays produced by a liquid-liquid coaxial swirl injector in a non-combusting environment. Phase Doppler anemometry is used for the measurement of velocity and Sauter mean diameter of droplets across and along the injection axis for various innerand outer mass flow rates. Results of the combined spray are compared with...

Visualization of high-speed gas jets and their airblast sprays of cross-injected liquid

A planar and instantaneous visualization study of high-speed gas jets and their airblast sprays was performed to qualitatively examine the different atomization performances of different gas nozzles. For the visualization of high-speed gas jets (with no liquid injected), Nd:YAG pulsed laser sheets imaged the clustered vapor molecules in the Rayleigh range (d@j), condensed from the natural humid...

Experimental Studies of Inverted - Profile Coaxial Jet Flows

The Primary Breakup of a Round Liquid Jet by a Coaxial Flow of Gas

Numerical simulations are conducted to investigate the primary atomization of a round liquid jet surrounded by a coaxial flow of gas. A Refined Level Set Grid (RLSG) method coupled to a Lagrangian spray model is used to capture the whole breakup process of the liquid jet. In the near field of the liquid jet, where the primary breakup occurs, motion and topological changes of the liquid jet are ...

Coal Disintegration Using High Pressure Water Jet

2 Research method Different methods of coal processing into fuel [1, 6, 12] usually require its intensive comminution. Such situation needs the creation of new technologies for coal micronization [4, 11, 17] that enlarge specific surface of coal micro particles what finally intensifies burning process of such coal dust. Some interesting effects of water-coal mixture ensure waterjetting technolo...
