【摘要】:水力噴射-空氣旋流器(WSA)是一種新型高效的氣液傳質(zhì)設(shè)備。為了深入研究不同氣速條件下壓力場(chǎng)與WSA壓降特性相互作用的影響情況,文中利用FLUENT軟件對(duì)水力噴射-空氣旋流器中壓力場(chǎng)進(jìn)行了數(shù)值模擬。數(shù)值模擬結(jié)果表明:在氣速等于16 m/s時(shí),壓力最大值區(qū)域分布最為對(duì)稱,該處氣液傳質(zhì)相關(guān)性質(zhì)的狀態(tài)趨于穩(wěn)定。湍動(dòng)能的最大值區(qū)域由耦合空間和分離空間向排氣管底部聚合。總的來(lái)說(shuō),靜壓值與總壓值差異不大,動(dòng)壓均值在耦合空間不同截面上的增減幅度比靜壓和總壓均值明顯。
[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.
