Numerical Simulation of Gas Phase Pressure Drop in a Water-sparged Aerocyclone
摘要
Abstract
The gas pressure drop and flow field in a water-sparged aerocyclone was simulated using multiphase flow model of the volume of fluid (VOF)based on Reynolds stress model (RSM).The results indicated that the adopted model could better simu-late the gas phase pressure drop,liquid phase reflux ratio and the jet-cyclone coupling field.The gas phase pressure drop of the WSA could be divided into three different zones,i.e.low pressure drop zone,pressure drop jump zone and high pressure drop zone.The water jet maintains the integrity preferably in the low pressure drop zone while the water maintains the jet atomization like bag breakup in the pressure drop jump zone and the water maintains the jet atomization like shear breakup in the high pres-sure drop zone.The pressure distribution in the WSA is almost symmetrical axially,and the highest pressure zone exists in the top part of the coupling field,the lowest pressure zone lies in the inlet area of the ventilation tube and the pressure of the sepera-tion space is moderate.关键词
