水力喷射-空气旋流器中压力场的数值模拟
Numerical simulation of pressure field in water-sparged aerocyclone
摘要
Abstract
The water-sparged aerocyclone (WSA) was a new and efficient gas-liquid mass transfer equipment.In order to study the impact under different conditions gas velocity field and pressure drop characteristics of the interaction of the WSA,using the FLUENT software simulate the pressure field of WSA.By numerical simulation of WSA pressure field,when the gas velocity is 16 m/s,its maximum pressure region is most symmetrical distribution,which illustrates related properties of gas-liquid mass transfer stabilized state.Probably gas-liquid mass transfer results from steady to unsteady slowly transition to maximize the effect of mass transfer.Generally speaking,with the increase of gas velocity,turbulent kinetic energy distribution of the symmetry in each cross section gradually weakened.With the gas velocity changes gradually,the area of the separation space maximum turbulent kinetic energy distribution gradually take polymerization near the bottom of the exhaust pipe.Overall,on the different cross section of the couple spatial the increase or decrease in the mean dynamic pressure significantly higher than the static pressure and total pressure,static pressure and the total pressure value is insignificant.Different cross-sections of the dynamic pressure in the WSA coupling space,drop kick zone exhibits abruptly phenomenon.关键词
