通过恒温水浴振荡器使静态溶解平衡的二氧化碳-水体系中的流体产生回旋运动,以此研究流体的流速对二氧化碳-水体系静态溶解平衡的影响,从而归纳出了二氧化碳和水的动态溶解平衡状态.采用示踪法测出振荡器不同振荡频率对应的流体的回旋流动线速度,进而计算流体的雷诺准数以考察流体运动状态.实验结果表明,流体的流动引起二氧化碳-水体系远离原有静态溶解平衡.在常温25.5℃下,原有静态饱和状态下溶解在水中的二氧化碳的量约有6.55%被解吸出来,亨利系数可产生高达15%的偏差.

By means of an oscillator, cyclone motions can be induced in a liquid. The effects of varying liquid ve-locity on the static dissolution equilibrium in the carbon dioxide-water system have been studied. Using the trac-ing method, cyclone velocities with different oscillation frequencies have been measured, and the Reynolds num-ber of the liquid calculated in order to analyze the turbulent intensity. The experimental results show that turbu-lence of the liquid can make the carbon dioxide-water system move away from its initial static equilibrium. At 25.5℃, about 6.55% of the dissolved carbon dioxide escaped from the system, and Henry's law constants showed a deviation of up to 15% compared to the static dissolution equilibrium.
