| 1 | 微细颗粒强化气液传质研究综述显示文摘气液传质广泛存在于气体分离等化工过程中,强化气液传质有助于实现高效率低能耗的生产。在气液两相体系中加入第三分散相固体颗粒是强化气液传质的一个重要方法。该文对微米颗粒及纳米颗粒强化气液传质的实验和理论研究成果进行了总结与比较,对目前的研究中存在的问题进行了分析。在传统气液传质理论的基础上,阐述了3种被学者广泛认可的颗粒强化气液传质的机制,简单介绍了几个可以微观上解释颗粒强化气液传质现象的均相和非均相模型,比较了它们的使用范围和准确度。最后,在对已有文献综述的基础上对纳米颗粒强化气液传质的研究方向进行了展望。 | 姜家宗 赵博 曹萌 禚玉群 王淑娟 | 2014 | 中国电机工程学报2014，34，5： | 8 |
| 2 | Experimental and Theoretical Studies of CO2 Absorption Enhancement by Nano-Al203 and Carbon Nanotube Particles显示文摘The influence of nano-particles on CO2absorption was studied experimentally in a stirred thermostatic reactor.Nano-Al2O3and carbon nanotube(CNT) particles which showed different hydrophobic properties were chosen for the investigation.The experimental results were compared with that of micron-size activated carbon(AC)and Al2O3particles.From the results,no enhancement by micron-size Al2O3was found,and with the increase of Al2O3concentration,the enhancement factor decreased.However,nano-Al2O3showed a weak enhancement for the CO2absorption.AC and CNT particles all intensified the gas-liquid mass transfer effectively,yet the trend of the enhancement factor with stirring speed for the two particles was different.With increasing stirring speed,the enhancement factor of AC particles was decreased,whereas in CNT suspensions it was increased.The experimental phenomena demonstrated a difference in enhancement mechanism for different size particles.For nano-particles,besides the influence of adsorbability and hydrophobicity,the micro-convection caused by Brownian motion should be also taken into account.Considering the micro-convection effect,a theoretical model was developed to shed light on the absorption enhancement by nano-particles. | 卢素敏 邢敏 孙燕 董相均 | 2013 | Chinese Journal of Chemical Engineering2013，21，9： | 7 |
| 3 | T型微通道内液滴形成过程及长度的实验研究显示文摘利用高速摄像机研究截面为400×400μm的正T型微通道内液-液两相流动特性,离散相(硅油)和连续相(质量分数为0.5%的十二烷基硫酸钠SDS蒸馏水)的体积流量范围分别为1~5、2~110 mL/h.结果表明,两相流型主要为弹状流和滴状流,前者的形成机理为挤压机理,后者为剪切机理.液滴的长度随离散相体积流量和离散相与连续相体积流量之比的增大而增大,随连续相的体积流量和毛细数的增大而降低.液柱长度的变化规律与液滴长度相反.液滴生成时间随离散相与连续相的体积流量的增大而逐渐降低,剪切机理生成液滴所需时间小于挤压机理.依据实验结果,采用离散相与连续相体积流量比和连续相的毛细数,总结出无量纲液滴、液柱长度及液滴生成时间的预测关联式. | 张井志 陈武铠 周乃香 雷丽 梁福顺 | 2020 | 浙江大学学报(工学版)2020，54，5： | 3 |
| 4 | 对称分支并行微通道中气液两相流的均匀性规律显示文摘采用高速摄像系统研究了对称分支形并行微通道内气液两相流及弹状气泡均匀性规律。实验中分别采用含0.3%SDS的甘油-水溶液与氮气作为液相和气相。观察到弹状流和泡状流两种流型,作出了由两相操作条件构成的流型图及流型转变线。结果表明,气泡非均匀性主要由两微通道内流体之间的相互作用、下游通道中流体动力学的反馈作用以及通道制造误差造成。随液相黏度增大,气泡均匀性变好;在高液相流量以及低气相压力下操作,气泡尺寸分布更易达到均匀。基于压力降守恒原理和微通道内气液两相流阻力模型,构建了两通道中气泡尺寸的预测模型。 | 沈秋颖 Tahir Muhammad Faran Cumbula Armando José 付涛涛 姜韶堃 朱春英 马友光 | 2018 | 化工学报2018，69，11： | 1 |
| 5 | Process intensification in vapor–liquid mass transfer: The state-of-the-art显示文摘The concept of process intensification(PI) has absorbed diverse definitions and stays true to the mission—'do more with less', which is an approach purposed by chemical engineers to solve the global energy & environment problems. To date, the focus of PI has been on processes mainly involving vapor/liquid systems. Based on the fundamental principles of vapor–liquid mass transfer process like distillation and absorption, there are three strategies to intensify interphase mass transfer: enhancing the overall driving force, improving the mass transfer coefficient and enlarging the vapor–liquid interfacial area. More specifically, this article herein provides an overview of various technologies to strengthen the vapor–liquid mass transfer, including application of external fields, addition of third substances, micro-chemical technology and usage of solid foam, with the objective to contribute to the future developments and potential applications of PI in scientific research and industrial sectors. | Hong Li Chuanhui Wu Zhiqiang Hao Xingang Li Xin Gao | 2019 | Chinese Journal of Chemical Engineering2019，27，6： | 1 |
| 6 | 并行微通道内液液两相流及介尺度效应显示文摘使用高速摄像仪研究了T形并行微通道液液两相流的流型。以甘油-水溶液为分散相、含5%(质量分数)道康宁的硅油为连续相,下游通道中观察到了塞状流、液滴流、环状流和并行流4种流型,绘制了流型图及流型转变线。研究了后空腔中液滴群的形态,运用介尺度概念分析了后空腔中液滴群的行为对流量分配的影响。观察到后空腔中液滴群的挤压、松散、有序排列和并行排列等4种形态,不同形态的转变主要受两相流量比的控制。研究了两相流量比对并行微通道内流量分配的影响,以及分析了不同操作条件下影响流量分配的主导因素。在两相流量比较小时,流量分配由下游通道的流体阻力主导,而两相流量比较大时由后空腔内液滴群动力学主导。 | 王忠东 朱春英 马友光 付涛涛 | 2022 | 化工学报2022，73，6： | 1 |

| 8 | T型微通道内浆料体系中气泡生成行为与尺寸预测显示文摘实验研究了T型微通道内浆料中气泡的生成过程和尺寸。聚丙乙烯微球浆料和N2分别为连续相和分散相。气泡的生成过程可分为三个阶段:膨胀阶段、挤压阶段和快速夹断阶段。随着浆料浓度的增大,膨胀阶段时长几乎没有变化,挤压阶段显著缩短,而快速夹断阶段略有缩短。在膨胀阶段和快速夹断阶段,气泡颈部宽度与无量纲剩余时间均呈幂率关系,而挤压阶段气泡颈部宽度与时间呈线性关系。考察了浆料浓度、气相和浆料流量对气泡生成尺寸的影响。结果表明气泡尺寸随气相流量的增大而增大,随液相流量和浆料浓度的增大而减小。 | 陈祯 刘静 朱春英 付涛涛 马友光 | 2021 | 化工学报2021，72，2： | 0 |
| 9 | 微通道内表面单孔的空心硅铝复合微球的制备(英文)显示文摘Si/Al composite hollow spheres with a surface hole were prepared with the co-axial microchannel in a one-step method. It is easy to use the technique for size control and continuous operation. At Si/Al ratio between 4 and 5, a hole forms on the surface, due to the fast gelation process and high viscosity of the sol. Scanning electron microscopy, nitrogen adsorption–desorption isotherms, and mercury intrusion method are used to characterize the samples. The hole size is 40–150 μm and the particle size is 450–600 μm. The size can be adjusted by the flow rate of the oil phase. | 王晋媛 王玉军 骆广生 | 2014 | Chinese Journal of Chemical Engineering2014，22，Z1： | 0 |
