摘要

纳米制冷剂能否强化管内沸腾换热，El前尚无明确的结论．将配制0．1 g／L的CNTs／R141b纳米制冷剂在内径为8．12 mm的水平光滑圆管内进行沸腾换热实验，光管采用电加热丝进行恒热流密度加热．纳米制冷剂采用HCFC141b混加碳纳米管，体积密度为0．1 dE．实验测试范围为：(i)质量流速为95．7～382．9 kg／(ITI ·S)；(ii)热流密度为5～20 kW／m ；(iii)人口干度为0．1～0．8．考察了质量流速、千度及热流密度等因素对纳米制冷剂管内沸腾换热的影响．实验结果表明：在低质量流速(95.7 kg／(m ·s))下纳米制冷剂能够强化管内沸腾换热，随着流量及平均干度增加，纳米制冷剂强化换热的效果将会变小，甚至引起换热恶化．

Abstract

It is not clear whether Nano-refrigerant can enhance boiling heat transfer in tubes．It investigates experimentally nano—refrigerant boiling heat transfer in a horizontal smooth tube(8．1 2 mmlD)，a tube uniformly heated by electric wire．The nano-refrigerant was HCFC141 b mixed with CNT and its volume concentration was 0．1 g／L．The experimental tests were carried out under the following conditions：(i)the refrigerant mass fluxes within the range 95．7～382．9 k (m ·s)；(ii)the heat fluxes within the range 5～20 kW／m ；(iii)the inlet vapor qualities from 0．1 to 0．8．The effects on measured heat transfer coeficient of mass flux，imposed heat flux and inlet vaporquality were examined in detail．The experimental results show that the nano—refrigerant will enhance boiling heat transfer within small mass fluxes(95．7 kg／(m ·s))．However，its effect will be weakened or it will even reduce heat transfer coeficient as the mass fluxes and vapor qualities increase．
