【摘要】：水力喷射-空气旋流器(WSA)是一种新型高效的气液传质设备。为了深入研究不同气速条件下压力场与WSA压降特性相互作用的影响情况,文中利用FLUENT软件对水力喷射-空气旋流器中压力场进行了数值模拟。数值模拟结果表明:在气速等于16 m/s时,压力最大值区域分布最为对称,该处气液传质相关性质的状态趋于稳定。湍动能的最大值区域由耦合空间和分离空间向排气管底部聚合。总的来说,静压值与总压值差异不大,动压均值在耦合空间不同截面上的增减幅度比静压和总压均值明显。
[Abstract]:Jet air cyclone (WSA) is a new type of gas-liquid mass transfer equipment. In order to study effects of different gas velocity under pressure and WSA pressure drop characteristics of the interaction, the water jet pressure field air cyclone were simulated numerically by FLUENT software. The numerical simulation results show that the gas velocity is equal to 16 m/s, the maximum pressure of the symmetry for the regional distribution of the gas-liquid mass transfer properties of the state tends to be stable. The maximum area of turbulent kinetic energy by coupling space and separation space to the exhaust pipe at the bottom of polymerization. In general, static pressure difference and the total pressure, the dynamic pressure in the mean coupling different sections of the increase or decrease than the static and total pressure value is obvious.
