摘要

对单个气泡传质的近界面浓度场影响因素进行了实验和理论研究．实时激光全息干涉法测量结果表明，运动气泡近界面浓度是一个定态值，受流速、泡径、温度等因素影响显著；假设该传质过程达到局部平衡，进行热力学分析，得到的结论与实验结果一致．在实验测量结果的基础上，对单个O_2气泡在乙醇中吸收时的传质近界面浓度场进行了数值模拟，取得了良好的结果．

Abstract

In order to afford an insight into the problem of bubble mass transfer

this paper experimentally and theoretically deals with the effective factors of near-interfacial mass transfer of a single bubble.The micro real-time holographic interference results showed that near-interfacial concentration is a stable value of dynamic mass transfer.It was affected by relative velocity

bubble dianmeter

temperature

pressure

etc.The thermodynamic analysis of the bubble mass transfer got the same result as experiment.Nunerical simulation of the near-interfacial concentration field of a single CO_2 bubble absorbed in alcohol was made.
