Numerical Simulation of Factors Affecting Rotary Atomization of High Salinity Produced Water in Gas Fields
The more concentrated the droplet size after atomization,the more easily the atomization process is controlled.Adjusting atomization parameters can reduce the operating cost of the produced water system of gas field and improve the treatment effect.In this paper,the coupled gas-liquid two-phase turbulence theory,discrete phase model and TAB(Taylor Analogy Breakup)model were used to build a Lagrangian method based rotary atomization model to conduct numerical simulation on the atomization process of high salinity produced water of gas fields,re-produce the droplet fragmentation process at different times,and obtain the velocity vector distribution of continuous phase air and discrete phase droplets.Then,the influences of rotary atomization speed,rotary diameter and liquid inlet volume were analyzed.The results show that the higher the rotary speed,the larger the rotary diameter and the less the liquid inlet volume,the better the atomization effect is.This study provides a theoretical reference for opti-mizing the structural and technical parameters of the rotary atomizer.
