| 摘 要： | CO2气泡群在液相中的传质在化工过程中广泛存在.对CO2气泡群在3种不同流体(牛顿流体、非弹性剪切变稀流体和黏弹性剪切变稀流体)中的气液传质过程进行了研究.利用CO2探针测定了不同操作条件下CO2的体积传质系数,考察了液相浓度,气体流量以及流变性质对体积传质系数的影响.结果表明:在3种流体中,体积传质系数均随气体流量的...

| Abstract: | Mass transfer from CO2 bubbles swarm into ambient liquids is widely encountered in chemical process.The mass transfer process of CO2 bubble swarm in three kinds of fluids(Newtonian fluid,inelastic shear thinning fluid and viscoelastic shear thinning fluid) was studied.The volumetric mass transfer coefficient was measured experimentally by using CO2 probe.The effects of the liquid concentration,gas flow rate and rheological property of non-Newtonian fluid on the mass transfer of bubble swarm were analyzed.Th... |
