摘要
实验测定了有油和无油工况下,CuO纳米颗粒在CuO-R113纳米制冷剂沸腾过程中的迁移量。结果表明:在CuO-R113纳米制冷剂沸腾过程中,无论是有油还是无油,CuO纳米颗粒的迁移量都随CuO纳米颗粒质量和制冷剂R113质量的增加而增加,迁移率随CuO纳米颗粒体积分数的增加而减小;油存在时,CuO纳米颗粒的迁移量和迁移率都低于相同情况下无油时CuO纳米颗粒的迁移量和迁移率。
Migrated mass of CuO nanoparticles in the boiling process of nanorefrigerant CuO - R113 with and without oil were measured. Experimental results show that the migrated mass of CuO nanoparticles in the boiling process of both nanorefrigerant and nanorefrigerant -oil mixture, increase with the increase of the original mass of CuO nanoparticles and the mass of refrigerant Rl13; the migration ratio decreases with the increase of volume fraction of nanoparticles; the migrated mass of CuO nanoparticles and migration ratio in the nanorefrigerant -oil mixture are less than those in the nanorefrigerant.
