摘要 设计了磁场强化氨水鼓泡吸收试验台并在此基础上研究了静止和旋转磁场及纳米磁流体对氨水鼓泡吸收的影响。通过对氨水鼓泡吸收的吸收率和有效吸收比分析发现磁场和纳米磁流体对氨水鼓泡吸收均有强化作用,而旋转磁场的强化效果比静止磁场更为明显。定义了旋转强化吸收量(ARMF)的概念以表征在其他条件相同时磁场的旋转对氨水鼓泡吸收的强化影响。在不同磁感应强度下ARMF的值均大于0,说明磁场的旋转对氨水鼓泡吸收均有强化作用。最后探讨了实验中出现结果的可能机理。 The effect of rotating magnetic field and ferrofiuid in NH3/H2O bubble absorption process was studied. The comparison of absorption rate and effective absorption ratio between still and rotating magnetic field was carried out. The results showed that the NH3/H2O bubble absorption can be strengthened by rotating magnetic field and ferrofluid. The enhancing influence induced by the rotating magnetic field was more effective than that of still magnetic field under the same conditions. The notion of absorption by rotating magnetic fluid (ARMF) was defined to characterize the effect of the rotating of the magnetic field in NH3/H2Obubble absorption process. The result that the ARFMs were all above 0 showed that the rotating of the magnetic field had positive effect in NH/H2O bubble absorption process. The possible mechanisms for the phenomena in experiments and related results were also explained.
