摘要

为探讨纳米流体对氨水鼓泡吸收传热传质特性的影响，利用自行设计的实验系统进行了不同浓度单体Ag纳米流体基液下的氨水鼓泡吸收实验。实验表明：纳米流体浓度与初始氨水浓度是影响鼓泡吸收过程中传热与传质的关键因素。当单体Ag纳米流体在浓度0.005%～0.020%内、基液中没有添加纳米流体时，5 min内随着时间推移，吸收器内溶液温度明显高于添加有纳米流体的情况;氨水鼓泡吸收传质过程中，有效吸收比均大于1.0，随着氨水浓度上升，各浓度纳米流体基液下吸收率逐步减小，有效吸收比逐渐增大，且吸收率和有效吸收比均随着纳米浓度增大而上升，当氨水浓度为20%且纳米流体浓度为0.020%时，单体Ag纳米流体强化氨水鼓泡吸收有效吸收比达到最大值1.55。对实验现象和相关结论进行了可能的机理解释。

Abstract

The effect of mono nano Ag on the heat transfer and mass transfer characteristics in NH3/H2O bubble absorption process is studied.The experiments show that the concentration of mono nano Ag in the nanofluid and the concentration of ammonia in the base-fluid are the key parameters.The temperature of solution with mono nano Ag in the absorber is higher than that without any additives.In the mono nano Ag concentration range of 0.005%—0.020%

the effective absorption ratio is always higher than 1.0 and gets larger with the increase in the initial ammonia concentration

and both the absorption rate and effective absorption ratio increase with the mono nano Ag concentration.It is also found that the effective absorption ratio can reach the maximum 1.55 when the initial ammonia concentration is 20% and the mono nano Ag concentration is 0.020%.Therefore

it can be concluded that the addition of mono nano Ag enhances significantly the absorption in the ammonia bubble absorption process.The possible mechanisms for the phenomena in experiments and related results are also explained.
