中文摘要：

实验研究了水平圆管内CuO-水纳米流体在层流区的流动特性，CuO纳米颗粒的质量分数为0．5％、1％、2％，平均温度为30℃、40℃、50℃，实验研究表明：在本试验范围内，流动阻力的大小同温度的升高呈现降低趋势，而随质量分数的增加变化不大。

英文摘要：

Laminar flow characteristics of CuO-Water nanofulid in horizontal mini-tubes were investigated experimentally, with the mass fraction of 0.5%, 1%, 2% and average temperature of 30℃, 40℃, 50℃ respectively. The results indicate that flow resistance decreases as temperature increases, but few effects of mass fraction are found.
