The normal injection of a liquid jet into a gaseous crossflow has many engineering applications. In this thesis, detailed numerical simulations based on the level set method are employed to understand the physical mechanism underlying the jet ``surface breakup''. The numerical observations reveal the...
Three-dimensional flow structures and droplet-gas mixing process of a liquid jet in supersonic crossflow The mixing process of a liquid jet in supersonic crossflow with a Mach number of 2.1 was investigated numerically using large eddy simulation (LES) based o... P Li,Z Wang,XS Bai,... ...
Abstract Based on the large eddy simulation method, the simulation model of annular swirling viscous jet was established and the breakup process and surface wave of annular swirling viscous jet were studied. The results show that the difference of velocity distribution between gas and liquid will lea...

2) jet length 射流长度 1. Based on electrostatics and charged principle of liquid,the properties of jet area,transient area and atomization area were given for charged oil in a high voltage electrostatic field and jet length,atomizing angle and oil particle size distribution were main factors ...
An experiment was conducted to investigate the surface stripping and breakup lengths of a round water jet.The process of the main and the satellite droplets in Rayleigh model was further studied under low jet velocity.With the increase of jet velocity,small droplets were stripped off from the jet...
Breakup Behavior of Liquid Metal Jet into Stationary Water with Electric Atmosphere Control (Simulation Study of Metal Particle Production Process) Liquid gallium jet was injected from glass capillary into stationary water layer and the breakup behavior was observed in detail, as a simulation study of...
interface of gas-liquid,which is considered as the main factor that leads to instability on surface of droplet and then break into small drops;the viscosity of droplet take a suppressive role to disturb wave,and the acceleration at interface of gas-liquid is important factor in breakup of ...
The high-speed digital imaging system is employed to record the unsteady dynamics when the liquid jet breaks to form mono-disperse or poly-disperse drop size distribution depending upon the atomizing air to liquid jet momentum ratio. The coherent spatial nature of the atomization process is ...
The breakup of a laminar liquid jet is the underling phenomena used to generate emulsions in micro-scale devices. Jet breakup is induced by the most unstable disturbance growing on the jet surface, and linear instability analysis can be utilized to predict the resultant droplet size. Previously, ...
