| 摘 要： | 基于Danckwerts的界面更新模型和Langevin方程,分析了纳米颗粒对氨水鼓泡吸收性能影响的非均相膜传递和液相内传递过程,初步解释了纳米颗粒强化氨水鼓泡吸收性能的机理.认为纳米颗粒对氨水鼓泡吸收的强化过程包括液相强化和界面强化两个同时进行的子过程,而对于界面传递,由于纳米颗粒引起的Marangoni对流,使其强...

| Abstract: | Based on the Danckwerts interface refresh matrix and Langevin equation,the influences of nanoparticles on the heterogeneous phase film transfer process and liquid phase transfer process of ammonia bubble absorption were analyzed preliminarily,which can explain the mechanism of nanoparticles enhancing ammonia bubble absorption performance reasonably.According to the analysis,it was found that the process of nanoparticles enhancing bubble absorption performance includes two sub-processes of liquid phase trans... |
